Lots of good stuff posted here. Not much I can add but to make sure you are only paper tuning at about 10 yards. You want to check the flight off the bow, not after the fletching takes over. Something else, you might have someone else shoot it to make sure you are not torqueing the bow. I had a buddy one time tune his bow to death, when all was wrong was his form. Also, ive found a slight high tear is desireable. If you set you bow with a slight high tear, your fixed broad heads will fly like a champ. Or that is what I have been setting my bows at for over 10 years. All ive had to do to before hunting season is to spin test my broad heads, and if they are true, they will always fly like my field points. Dont get me wrong, I still shot a couple of broad heads to make sure the are flying right, but I have not had to do any adjusting in over 10 years.
