Anyone you know have one that you could try? What I have observed is that people either love it or hate it. I have a trashed shoulder so I tried it because of the claims. I really like it, plus I'm a puncher so shooting with my middle finger has helped. It's a little cumbersome but it didn't take long for me to feel comfortable with it. Shooting it with an index finger didn't feel comfortable too me but I didn't spend much time trying.
I see a few on archerytalk for sale, you could pick one up cheaper. If by chance you are around Utah County you are welcome to try mine.
I assume you have seen Ulmer's video on it?
