All my squat gear is now Titan, I honestly feel like it has given me the best carry over. With that being said its not so much carry over as you want as hip health. The Titan Centurion box briefs are prob the best. Ken Anderson (andersonpowerlifting.com) can get you a set out really quick. You could always order a z suit from inzer and just never pull the straps up. Not really any carryover there, but will help with keeping the hips healthy. Personally I say Titan Centurion briefs....but I am a gear whore haha.
Best meet lifts: 1040squat, 730 bench, 730 deadlift
Best total: 1040-680-730=2450
