What thumb release do you recommend? I would just be using it for deer hunting, and practice of course.

Although I don't shoot one, you can not go wrong with a Stanislawski release. If I shot target archery with a lower poundage bow than my hunting setup, I would shoot one. Likely one with a thumb trigger.

I have a finger release with a wrist strap. I like the wrist strap to aide with drawing my bow especially on cold days.

I used a tru-fire last year. Worked well no complaints

I shoot a TRU Ball Max Hunter no complaints

Stan shootoff trio.
