Well I did it. I test drove my Metal Deadlifter today sumo style. Here's what happened.
Squats - 6 sets, 4 reps, 275lbs (every second set with knee wraps).
Bench Press - 7 sets, 7/6/5/4/3/2/1 reps, 215lbs +10lbs/set.
Sumo Deadlifts - 5 sets, singles, 365/405/455/495/555lbs!!!
I was totally impressed. After I lifted 495lbs, which was the easiest 495lbs I've ever lifted, I decided to go for a new PB. Probably not the smartest idea this close to competition. But, now I know. I'll be lifting sumo in November and I'll make a run at 600lbs (275kg). I also wanted to try my knee wraps a bit more. They seemed to be way more comfortable today then they have in the past. I just wrapped them medium tight from below the knee to above. I think I may use them for sumo deadlifts as well as squats.
