Thanks guys! I did use a Metal King Deadlifter. FWIW I don't put it on to tight. No more than an old supersuit in the old days. I can't guess on my carryover. It's not two pounds, but it's not fifty either. The biggest benefit to the suit is it reminds me to get my hips down. I tend to let them up to high when I lift raw.
It's a great cue for positioning. I might give it a go raw soon also when I test, or just shoot for 625-650. Josh has built up my floor speed a lot which was the area where I would normally miss.
