I've always considered tip shape to have lesser impact vs shaft diameter. I do like a more rounded "edge" but not extreme (from Nickel). The smaller in diameter ya go, the more precise ya gotta be, or more like less effort (exaggerated result) = less forgiving. Absolutely enjoyable! Be Safe

[@shanesoldner9117]

Great video Dave! This helps explain a problem I had with randomly switching cues. I shoot what I called tips but I really only have the numbers zero to three. And three is only rarely used on longer low stun shots or close shots that are shot slowly with a lot of spin. 2 is where I live for most draws and force follows. But most of my game is between zero and one. Now I understand why trying cues with different shaft thicknesses was difficult for me. I was always able to do fine as long as I didn't get very far out of center.

Thanks. I’m glad you found it helpful.

[@DrDaveBilliards]

[@dd0ck]

Really great video of a topic full of myths (I think) because it’s so subtle and it’s mostly trial and error. Thank you for sharing! I wish I had watched this prior to moving from a 12.9mm shaft with nickel radius to a 12.2mm shaft with a dime radius, one of the things that took me the longest to adjust to was the change in tip offset from center to get the same amount of spin. It would have been good to know this going in, instead of going through all the frustrations of recalibrating without knowing the root cause of the issue! (I actually use a 14mm Mike Gulyassy ‘Frankenstein Shaft’ now with a quarter radius and I love the stiff hit and am still able to spin the cue ball as much as with any other cue I’ve played with and the thicker shaft feels better in my bridge and I much prefer the stiffer hit than the tiny diameter shafts that are gaining popularity. Goes to show the myth of ‘smaller shaft, rounder tip = more spin’ ain’t really true. I heard Earl Strickland was (before signing with JFlowers) using the 15mm version of the ‘Frankenstein Shaft’ and was still playing at a high-level-it’s the shaft he used at his latest Mosconi Cup appearance.)

[@ricklava8850]

What about with shaft aiming edge to edge? When using side spin does a biger shaft gives you less side spin compared to a smaller shaft?

[@DrDaveBilliards]

All that matters is where the tip contacts the CB during the stroke. If you hit the CB farther out, you will get more spin, regardless of the shaft size and how you arrive at your desired line of aim. I use SAWS to get an accurate line of aim for any shot with sidespin, and the shaft diameter does not matter: billiards.colostate.edu/faq/sidespin/aim/saws/

[@Derek_1111]

I switched to a BK Rush awhile back and immediately was having issues with getting way too much spin on the cue ball if I didn't hit perfectly center vs my old break cue. I'm assuming it's mainly due to the rounder tip and smaller diameter size... is it common for people to purposely shape their break cue tip more flat to help prevent the unintentional spin?

[@DrDaveBilliards]

Yes. Break cue tips are usually shaped flatter.

[@BansheeBunny]

0:43 There are cue tips and tools available that don't wear down your tip. The caveat is that the longer you use the tip the harder it becomes from impacting the cue ball. I use Kamui Black SS and their Drangons Tongue tool. Edit: Nickle round on a 12.5mm shaft.

[@DrDaveBilliards]

Tips also wear down with chalk use and play.

[@graemehirstwood670]

There is a a soccer/football boot that has been popular since the late '90's - the Adidas Predator. It utilises rubber ridges along the instep which improves the amount of curve that the footballer gets from a kick. Does a layered tip have a similar effect - increasing spin - in comparison to a standard tip?

[@DrDaveBilliards]

No. All playing tips grab the CB equally well (assuming they hold chalk).

[@joedel9337]

Dr.Dave I just got a break cue and it’s hard tip and is it okay for me to use a scuff and ruff it up. It seems chalk doesn’t apply all on the tip and doesn’t stay. I need help Dr.Dave

[@DrDaveBilliards]

Hard thread cue tips (especially phenolic) don’t hold chalk as well, especially some of the new “premium” chalks. I use Master chalk on mine and chalk carefully. It works fine. Scuffing really won’t help much.

[@claykuppinger]

Hey Dr Dave! I recently replaced my cue tip to a kamui clear. I shaped to where I like it, but noticed the tip is significantly taller than anyone I play with. Mine is almost a centimeter tall after shaping. Should tip length/shoulder be cut down? Or is that a natural consequence of maintenance and wearing down?

[@DrDaveBilliards]

I wouldn't trim it down. It will last longer the way it is, as it wears down with chalking and periodic shaping.

[@claykuppinger]

@@DrDaveBilliards thank you! Your videos have demystified so much of the game for me

[@M0J0HAND]

Coming back around to this topic, I was playing league play and asked one of the higher rated players on the team what type of tip he used. He claimed he has been using the tip that came on the cue and has been using it for many years without changing it. My interest isn't in the shaping but the hardness (no puns intended). When ordering a new cue, or a spare or new shaft for an existing cue, you get a choice of Super Soft, Soft, Medium or Hard. Can you give some guidance (or link to a video) that discusses the pro and cons of each and how they effect play?

[@DrDaveBilliards]

Good players can play well with any tip (assuming it holds chalk), but I prefer a harder tip per the info and videos here: billiards.colostate.edu/faq/cue-tip/hardness/

First off thanks for this and all your other videos. I have gotten a lot from them. This is slightly off topic, I apologize. I have a question about carbon fiber shafts. In your opinion is it normal and or acceptable to get black residue on your bridge hand at the contact point of the shaft and bridge? I play with an open bridge primarily and recently got a new cue from a reputable U.S. manufacturer. On the first day, after playing a few hours there was residue on my thumb and index finger. It has happened every time I play even after cleaning the shaft. Seems like that shouldn’t happen. Am I wrong?

[@DrDaveBilliards]

That is common, but it should happen less are some use and a few cleanings.

[@mikesheppard631]

@@DrDaveBilliards Ok, Thanks

[@ethanletzer3507]

Do you think the amount of tip on the cue makes a difference?? Like let's say we had two of the same exact cue. One has a brand new tip and the other is worn down to almost needing replacement. Would that make any actual difference in playability or in how the cue ball reacts off the tip??

[@DrDaveBilliards]

When a tip is used and not as tall, the tip effectively plays a little harder. For more info, see: billiards.colostate.edu/faq/cue-tip/hardness/ That's the only significant effect, but it is still a small effect.

[@crondawg101]

Thanks for this. I’ve heard some good players say they prefer a much flatter tip on their break cue. Do you have a view on this?

[@SliceNdicez]

3:56 flatter tips impart less unintentional spin. This allows you to send the cueball with more force while sacrificing accuracy as the unintentional spin imparted from the decrease in accuracy will be mitigated by the flatter tip.

[@DrDaveBilliards]

@@SliceNdicez Well stated. A flatter tip is definitely a good choice for a break cue.

[@tomaszsosnowski9279]

For novice and beginners, a flatter tip makes the game and tip maintenance easier. Ever wonder how after a stop shot the cue ball is spinning on the spot for a few seconds? With a flatter tip this unintentionally applied side spin causes less deflection thus increases shot making probability. If it were round, the deflection would make you miss the pocket. A round tip is great if you have Strickland level game.

[@DrDaveBilliards]

A flatter tip definitely reduces the chance for unintentional sidespin (as illustrated in the video). It also makes it more difficult to apply spin (side, bottom, or top) when you need it.

[@BeardedBilliards]

Is it fair to say that between two tips (one rounded to nickel and rounded to dime), playing a shot with each where they have the exact same tip position below center, exact same speed of the cue at the moment of contact, and exact same shaft diameter, that the one rounded to a dime would achieve more spin?

[@DrDaveBilliards]

Yes, but only very slightly more as clearly illustrated in the video.

[@BeardedBilliards]

@@DrDaveBilliards Okay, makes sense. Thank you Dr Dave! I just like to test myself for understanding sometimes, haha. Love the education you provide

[@JamesWII-fu7bt]

Dr. Dave, my question that I’ve not seen addressed on your videos is in the difference between a left-handed player and a right handed player or ambidextrous players

[@DrDaveBilliards]

Obviously, being ambidextrous is an asset; otherwise, there will be shots you won't be able to reach without an extension or bridge (whether you are right or left handed). Regardless of which hand you play with, the location of your personal vision center (especially if the cue needs to be on the body side of the nose) can make it difficult to find a comfortable stance with no neck tension, but this applies to any player. For more info, see: billiards.colostate.edu/faq/eyes/vision-center/ billiards.colostate.edu/faq/stance/

[@finkelmana]

Heck, cue tips dont matter at all. One of my favorite "that-guy-thinks-he-knows-how-to-play-pool" memories was this: Guy take a Dufferin cue off the rack on the wall. Rolls it along the table. Must be warped, so he puts it back. Does this several times. Finally, he finds one that he thinks is worthy. Then proceeds to play with it. It had no tip on it. Obviously, playing with no tip is better playing with a cue with a small warp.

[@DrDaveBilliards]

The tip is the most important part of the cue, even if the exact shape is not very important. My playing cue has a slight warp (due to the "less than perfect" joint extension), but it doesn't bother me one bit. The cue still hits the CB where I am aiming, and the CB still goes where I want.

[@finkelmana]

@@DrDaveBilliards I think you missed my sarcasm. :P

[@dddreeeeeee]

Is that true that everytime you change tip, the Diameter of the cue tip will reduce by size? So it will be smaller? I had 12.5mm tip. I changed my tip to the guy i know, and after 2 times changing tip with him, i bought the same shaft with the same diameter, but once i compared them side by side i recognize that the diameter is quite different. Is it the guy, who changes the tip bad, or is that normal?

[@walkeronegaming]

if 2 tip changes results in a noticeably thinner shaft you have a bad tip guy

[@DrDaveBilliards]

Sure it would. It would have even less CB deflection since it could not apply much sidespin, even with a larger tip offset from center (if the tip is really flat).

Dr Dave answering the question we all want to know: does size matter?

[@DrDaveBilliards]

I knew comment like this were "coming."

[@SliceNdicez]

I think straight out saying that it does not matter in the intro is very misleading. While it is possible to achieve all sorts of spin with varying sizes and shapes (except backspin), using a different cue definitely affects the way you have to play to achieve the same spin. So, I think it would be more accurate to say: it affects the way you have to play but it does not limit what you can do.

[@DrDaveBilliards]

Everything “matters,” but I think the video clearly shows that the differences in commonly used tip shapes are mostly unimportant.

People get that impression because they get used to their own shaft and don't really make a real effort to test this stuff with anything much different than what they're used to. But think about it this way: if you hit the same spot on the cue ball, how does the cue ball "know" that the rest of the tip is round or fat or skinny or whatever? The rest of the tip isn't touching it. Only the part that touches it has any effect. All the stuff that isn't touching it... doesn't matter what its shape is or how round it is. All the cue ball knows is where it was hit, and how hard.
