Depth looked great on the squat Brute, but I thought it was a bit Good Morning-ish with forward lean. Staying more upright is tough. I had the same problem awhile back and Steve suggested a High Bar Squat, which worked for me, along with a few other adjustments. I am sure he will be able to give more advice on it.
815 Rack Pull is out of this world!! Wow!! I have never dated anyone with an 800+ pull before!! I may have to put my tail between my legs when we max attempt!!
