Who's shooting a back tension? I use a old stan 4 finger my dad gave me. What kind do you guys use and why do you like it?

I'm shooting a Scott Longhorn Pro Advantage. I love it, it has a smaller, tapered handle. Solid brass so it also has a nice weight/feel to it. I love it, I'm trying to pick up another BT and a thumb release though. I'm wanting a Tru-Ball HT backtension, and a Tru-Ball ST-3. I'm thinking about hunting next year with the ST-3.
