I have two of the Winn Free Flight releases; the C-10, which shoots off the string, and the Loop release, which obviously is used with a string loop. These are great releases and you likely won't have to adjust your drawlength when switching from fingers. The only downside is they do tend to limit what you can do with your release hand, since the head doesn't fall away from the hand like most releases.
I have used this release for 10 years. It is very dependable but does limit your grasping capabilities. I am using my same release I originally purchased so they last.
