I have the 4 finger model. I have experienced the same issues you have. I am currently adjusting the tension down trying to get it to go off sooner. There have been a couple of times I was pulling so hard I was shaking and could not get it to go off. You are right theough, when I get it right, it is sweet. I think hand position has nmore to do with it than anything. I do intend to use mine for hunting. It has all of the qualities I have been looking for in a hunting back tension release. A wrist strap, and a trigger so I at least have some control over when it fires. I have a Stan 4 finger, but I have never been able to overcome the "what if" scenario of not having control over it in the heat of the moment.

I may try the 2 finger version as well.

Overall I ampleased with it too. I hope I can get the trigger adjusted to my liking and I'll be a happy camper.
