I don't squat heavy, but I can see the benefits. Ever done any box squatting? Anyways, the reason I don't squat right now is that I'm focussing on my posterior chain, before returning to the squat. Deadlifts, Romanian deadlifts, GH raises, Kneeling Hip Extension (the one you can find on tmuscle and that's great when it comes to improving hip function - not the sissy move that is useless), those are the things I'm doing right now.
