RE: Which thumb release?
I have a Pro Diamond T-handle, True Fire Hunter, Carter BK Hunter and just bought a Stan Super X. They all shoot good but I still seem to like the wrist strap releases for hunting. I find it hard to shoot the T-Handle thumb tigger releases with gloves on. The Super X shoots well but it is more for target shooting and I wish I didnt buy it. You asked about the Talon head compared to the caliper head. I think the caliper head is better for hunting. I find it easier to hook to my loop quickly.
