Lots of threads concerning beer league equipment. Do a search for more in depth talk. But quickly, imho, if you're playing in a lower level league, you may still want pretty good protection, particularly the shins, pants, elbows, and helmet, since there tends to be more accidental collisions and errant sticks in lower level play. Most modern equipment provides pretty good protection and mobility. Check out CCM QLT or if it's still around, the RBZ line (which I think is some of the best equipment in recent memory that had the combo of protection, lightweight, and mobility)
