I'm just an average diver but I am very interested in side mount. I'm pondering making a SM rig out of my Transpac, and was wondering about the reason for the butt plate. I usually sling a pony, and clipping it to my chest D ring and waist D ring keeps it in a position much like side side mounted tanks. Does the butt plate just pull the tank a little tighter to your body or what?
