I have the Trufire Hardcore thumb release. I have not hunted with it yet, but will target shoot with it some. I will say that I feel like I get a much crisper release with it and am more consistent with my anchor point. I really have not shot enough to feel comfortable hunting with it and I've never even brought it to a 3d shoot. It takes some getting use to. Mainly what was odd at first was that when you pull back with it all the weight is on your hand and your grip of the release and you are pulling it back, it feels a lot different from the weight of the draw just being on your arm/wrist with a wrist release. Also, you will have to refind where to anchor with it. But overall I like it and really should spend more time getting comfortable with it, I am able to shoot more accurately with it.
