I'm fairly new to picking but here's my understanding of it. Cheap Chinese locks with loose sloppy tolerances tend to not give feedback at all, and it's just mush. That *can* make it take slightly longer to pick vs a better lock with only standard pins. But just a handful of seconds at best. Those loose tolerances make it vulnerable and very easy to set the pins, even raking security pins can be really easy. Better locks with tighter tolerances will give much stronger feedback and have a more clear binding order, but that comes with being much harder to pick. You have to be very precise with tension and pick pressure to avoid dropping or oversetting pins when dealing with spools. They won't rake open as easily, and opening by raking alone is virtually impossible with security pins. So that's the trade off as I understand it. A good lock will put up a serious fight even if you can feel exactly what's going on inside of it. The ones loose enough to not have feedback, you won't need it. They'll open if you poke it with a paperclip.

@@ians5337 but wouldn't it be nicer to have a lock with pins that drop even when in tension? Key holds all pins at once in place, lockpick one by one. If one pin popped it has to fall back if there is nothing holds it
