DiveRite offers two choices to convert the transpac to side mount. One option being a square style tech butt plate. The other option is the triangle vesion like on the Nomad. Which one are people using? Does one seem to have more or less advantages. I am setting up for sidemount, I will be using 2 al80 tanks, I am a shorter diver 5'8" 200lbs if any of that helps. Just like to know which you think would be better.
