At the risk of being branded a heretic and blasphemer...I tried playing with releases. Experimented with both mechanical and non-mechanical.
My takeaway is that it depends on your shooting style.
I shoot instinctual (or whatever kids are calling it these days). I only hold at anchor for 1/10 second, or there abouts, and then pull through the release.
The releases don't work for me because I can't trigger the mechanicals at the right moment or toggle the non-mechanicals at the proper moment in my sequence.
Now, if you're a guy who holds at anchor until you feel the shot is right, then they may give you a consistent release. But it has no soul when you can't feel the string.
