RE: Thumb style releases?
I've shot QUIET a few different releases this year. I started hunting this year with a Tru Ball Pro Diamond. A cheap hunting thumb release. Not supposed to be the nicest thing out there, just for hunting. It was alright. I then went back a Scott Sabertooth to hunt with. I ordered a Carter Instatiable 3 a few weeks ago, and that's the one I'm liking right now. I'm shooting it really well. I'm also throwing in a Scott Longhorn Pro, pure Backtension to keep things in check. I used the Carter to shoot my 300 spot round a few days ago.
In all honesty, the Carter was my 2nd choice. I really wanted a Stan SX2 (Super X 2), but I couldn't get them through the shop, seeing as how it is a REALLY new release. It's AWESOME though, as soon as I can find a way to get one, that's what I'll be getting. They are just simply amazing. I love them.
