first meet was the 1987 cotton states/alabama championships.
I competed with just belt and knee wraps, won the teen division and beat the at the time teen national record holder who was also competing at that meet. weighed 212 lbs, teen division at that time was done by formula, not weight classes (the old now defunct ADFPA)
in my late 30's, I hit a 665 sumo dl with a suit. around the same time i hit a multi-ply suit, belt and knee wrap squat of 680, but that was a gym lift.
best total by formula was 600/365/600 (1565)as a ligt 198er (192lbs) in the early 1990s dont remember when exactly. this was a single ply with belt and wraps, no shirt.
