455 about 3 mos ago took me 5 full seconds to pull out of the hole but it seemed like a half hour and the back of my head felt like it was going to explode lol. 180 lb. bw. wide stance neoprene knee wraps cuz I have 2 previous knee injuries no belt.
best I've done is 700 for 5 at 396bw. am down to below 320bw now and I don't go over 500, but I've upped the reps/sets. I don't use wraps, but I always use a belt and occasionally use a single ply Inzer Z-suit.
