It can take awhile to learn releasing with back tension using an index finger release. You' ll know when you' ve done it, because it will startle you when the release goes off. It took me a lot of work to pull off this surprise release, on a consistant basis. Using back tension improved my shooting ability greatly, so it was worth the effort. A by-product of shooting with back tension that I' ve found, is that when I do have to take a shot a bit quicker at a deer that is not going to give me a big window of opportunity, I can do it much smoother than when I was punching my release. In other words, the punch is much more subtle when it only happens on occasion.
