I agree that it's all about the form & the process. With that yields consistency. I would shoot that back tension all the time if I was u & it was springtime. It would be nice to know more about the arrows. I think those r the skinnies with the blue vanes but I don't have a reference to judge them by. I've really found that with more weight up front like 140 instead of 120 helps with consistency. The arrow is more in control & not so touchy. The big thing is matching the # to them so your tune is perfect. 😅
When the damn wind is blowing I don’t even worry about where they hit I just concentrate on form. Getting the process properly done. I have a target at 30 yards without any spots on it. Wherever the pin settles? is just fine. I then just work on form and controlling the shot.
