I shoot an Insatiable2 for my thumb release... ITs really good IMHO and i love it. I mostly use my bt release but whenever i use anything else, its the thumb release. You can find them on AT in the classifieds for decent prices.

Rob- I know exactly what release you are talking about. I shot one a few months back. It was kinda weird to set at first b/c on his the pinky trigger was set as a safety.
