A lot of it also depends on how clean your form is when doing them. The more you use your legs the more weight you can move. With good form y Gm is 335 for a double and my raw sqaut is about 450 and raw dead about 500 of these done a few months ago.
Jay , i just started doing the suspended with chains and bands. I think that they are so much better than without bands/chains because of the increase in weihgt at the top. It really makes yoiu work throught the whole range of motion not just getting the bar moving. My best plain suspended is 315 a little below back parrallel. I think you should be able to almost touch your toes form a standing position and that is about where the bar should start. I think varying the hight as with any movement can be a good idea. You and jimmy will have two different heights to work at because he is like 6'2". I would say one week use yours and the next week use his.
