I don't know if you've ever seen sebastian burns pull but I pull with his style. I rolll the bar forward and when I roll it back towards me, I pull myself into my stance/start position. (I can't get into a good start position without doing this do to the suit)
I wonder if this would take some of the slack out of the bar as you mentioned? Taking the slack out of it would give you a higher start position but I wonder if overall it would hurt you inthat you would not be able to get the rip and momentum going?
I'll let you guys know what my expereicnce ends up being. My workout partner (John Paromba) pulls about 800 suited and is pulling in this meet. He said the okie bar should add 25 pounds or so to my DL.
