I’ve tried the Truball GOAT a couple of years ago and loved it but elbow tendinitis killed me with a thumb release. I think it’s back under control, so I’m going to go back to one. My local shop has these two and I know both companies make great releases with great warranties if you need them. The Truball is the Blade Pro which is half brass and I like the weight plus it’s a little more quiet for hunting. Not sure that it’s enough in a hunting situation anyway. Which do you prefer and why?
