Brian did you ask your body if it enjoys it raw as you shake like that, knees, hips, spine everything is under considerable strain with all that lateral movement, there is no capacity to lock it in and remain completely stable therefore you should give up the hard man act and use whatever makes your squat more efficient, but that same ego has busted up your entire body. I would be more impressed with seeing you squat 80kg with depth and perfect technique for 10 reps but fire away lets see how 6 reps looks with 315lbs.
