Went to the compound today and ran the rack a bit for Brian and JD. That's about all I'm good for. I did make some gear recommendations and my opinion is anyone who can squat 500 raw and is looking to move to multi-ply should use the Metal Ace briefs. They do take a little bit to learn but once you figure out making sure your knees stay out and you are really sitting back they will stop your descent. I like the a lot to because even with heavier weights when they wont "stop" you they provide good feedback to use to gauge depth.
