It was fine. Definately different......much more stress on my quads. I have done it before, but Rip was really able to twist and tweak my form until I felt comfortable. I probably need a little less heel than what I have. I think something between what I have now, and my chucks might be optimal. I will say this....435 felt better than 315.
I think there is a pic of my last set of squats under the SS events forum. Under the recaps thread.
