Arne, I am sure that I do not relax anything when I shoot, much to tense. When the snow leaves the yard, I am going to work on blind bailing with eyes closed until it happens. Needs to be second nature when I get the shot at the big 8 pter. Torquing the string is something I did not understand, your post helped when you said "tension will twist the string, both horizontal & vertical planes". The "control" comments were spots on, I have been called a control freak many times.
We can always count on you!
