Jeff pretty much hit on my view of the Carter wrist/index releases........if I were to use that style for 3D/target? I'd use one of the Carters since I would have the discipline and time to use it properly. Hunting situations don't always afford you that luxury and at least for me, I would get some wicked flyers that I never got with my Scott Rhino. I attribute that to the heavy no travel trigger. In the heat of the moment, if you punch it, or have to make it go off say if an animal stops for an instant in an opening.........in my case I didn't know what I was going to get.
I don't have the discipline to hunt with one, so I went back to my old friend the Rhino and that's where I am going to stay.

The Carters are a very nice piece of equipment.......I use the Thumb trigger styles for 3D, I just couldn't get used to the One-Shot in all hunting situations.
