There was a discussion on another forum regarding backtension and methods that the pros use to make them fire. There seems to be a lot of discussion about release rotation vs pulling totally with your back and making it fire. My own personal opinion is that a certain amount of release rotation is an absolute necessity in order for the release to fire. I don't think that just twisting your wrist is the right way to do it. That said, a relaxed grip on the release and less pressure on your index finger will cause a very slight rotation all while pulling with your back. Here's what Eric posted. To start with let me say that I strongly recomend setting a triggerless bt release with a good bit of travel. No disrespect to anyone who is successfull with a trigerless bt release and doesn't shoot this way, but I would say that virtually everyone at the top who is using a pure bt release is shooting it with travel. And...If your shooting it with travel you can not fire the release off back tension alone. You have to maintain back tension and that's important, but moving your hand and fingers is what makes that thing fire. The travel is important because it makes you stay active in the shot. You always keep pulling regardless of what the sight is doing. With a good bit of travel anticipation becomes a non-factor as well. For everyone who is shooting there release on the edge or have shot this in the past ask yourself this question. How many times have you been tenative with your release or had a hard time firing it in a pressure situation? Unless your lying to yourself this has happened to everyone who has shot a triggerless bt release set up light or with the clicker. Not to say it can't happen when you set them up with travel, but you know that you have to get after the release to make it fire so it forces you to be aggressive. I'll give you a great example of this. Nathan Brooks was in the shootoff in Vegas last year and let down after holding for a really long time. He got rid of the release in his hand and got a different one. After the fact I asked him what the deal was and he said he switched to a HEAVIER release. I was suprised at first, but when he explained it to me it made perfect sense. He was having problems getting it to fire and he knew once he swithed to something with even more travel that it would force him to be aggressive to get the release to fire. I know that this isn't going to work for everyone, but the topic came up so I figured I would add my thoughts.
