Me... wow.. going from a shitty suit (old inzer z suit) to a nice suit... yeah it makes a bit of a difference. Worked up to 500lbs tonite. It was a little high (needed to come down about two inches.. I think I was scared) but it came up like a rocket. I can't wait till this next meet. On a side note my fingers are fucking raw from getting that thing on. Without suit slippers I would have never gotten that thing on.
