John my front, overhead, sotts press and clean rack are all A2A. On my back squat I don't usually go that deep, still below parallel just not quite that deep when the weight gets heavier for me.
I am guessing that you see a transferance in muscle movement going that deep on the back and you also probably are doing a more upright O-Lift style instead of powerlifter style. So would you go slightly lighter and really drop down low versus going heavier and not getting that deep? I am asking the question relating to training in O-Lifts specifically.
By the way that is an awesome picture!
