i think training both styles is the complete package to carry over to greater athletic ability, since ideally, you'd be learning a greater amount of motor patterns (therefore having greater athletic ability? or am i just going on about something crazy?)
anyway, about squat strength vs clean numbers, there seems to be a point where full front squat or backsquat strength no longer carries over to clean numbers. i believe sportivny on dynamic-eleiko had an article regarding this. it was a very interesting read to say the least.
my point initially was that, i felt the full oly backsquat style is invaluable to the athlete, ESPECIALLY the beginner such as myself, and don't really like all the bad rap it seems to be getting lately regarding its carryover to other sports relative to PLer style squats. don't you just hate it when PLers call them "bodybuilding" squats?
anyway, this is really good conversation, much akin to those on fortified iron. this is the sort of stuff we should be talking about, not "how do i get a biceps peak?!"
edit: madcow, good to have you back
