I'm wearing Inzer Predator briefs. Almost a full size too big for me. They have incredible stopping power. When I don't roll the legs up and use a high bar, I can have trouble hitting depth with as much as 585 in them. They aren't for beginners in my opinion, the first time I wore them my knees were pulled in and I couldn't even hit a box. This was after occasionally using metal pro briefs for about a year. I love them, I bought them big on purpose to learn how to use them. After this meet I will get them taken in.
For the suit, I'm wearing a metal pro squatter. First generation/entry level multi ply suit. Honestly compared to the predators they are like tissue paper. But it is increasing my support and carryover and the legs are flared well to help me track my knees properly. I'm glad this is the suit I'm using for my first meet, it's helping me to feel everything out.
I have a Titan Boss waiting in the wings that will be a giant upgrade. I'm expecting 710-725 in this meet, but with tighter Preds, a winter with Donnie, and the Boss, I expect to be well over 800 this time next year. I've already been told as much by a near 1000lb squatter.
