I have a relatively high arch and bench single ply. I only use a belt on bench to hold my shirt in place, and don't latch it until I'm ready to go, shirt in place, and about to hit the platform. I use a 1-1.5" titan lever bench belt. I never use a belt raw. The best way for me to get my shirt and belt in place is to arch in warmups, have my shirt yanked down in the arch, and have it latched that way. I always have my shirt pulled down between attempts, too. The shirt slips so it needs constant adjustment. It hurts but is effective.
