I have the rush 72 and 100 and the condor one. The 72 is a great backpack. The 100 is a little too much, and them side pouches suck they don't come off easily. The condor is a backpack that wants to be a rush 72. But it is cheaper and not as nice. I keep that one in the car, so I don't have to worry if it gets stolen. The 100 is nice if you have a lot of hiking. The shoulder straps are nice to really adjust for yourself the perfect fit for hiking, and the waistbelt is very easy to remove. My pick go with 72. It's easier to grap and go.
