I'm gonna have to say T2... Dual pump arms! although the internal autorigger is cool and the reg configuration is by far the cleanest I've ever seen. I don't like the 88 frames they aren't very comfortable to me. Have you ever looked at the SM1?
This is my baby.. Meet Mr. Headshot..LOL! SM1 with Dye stickies, CP shorty, CP asa, Mad Man spring kit, (soon to be turbo valve) and J&J edge barrel. Smooth as butta..
