Once you get much better form and are really consistent with it you'll have learned more about tuning because you'll most likely be doing some along the way.
You know when ppl use to mention form I use to let it go in one ear and out the other, but I could tell a major increase in confidence on particular shots when my form was perfect. I can't describe it, I could tell I was looking straight down the arrow at the pins, my anchor point on my face was perfect, my release was perfect (did you know you can flinch shooting a bow? LOL), everything was perfect and I knew before the arrow hit, that it was going to be a perfect shot placement. I will get down out of the stand like you said, I love you guys advice, I just hope we can keep in touch till next year, I really want to do more bowhunting than gun next year. I was planning on doing a little thisyear before the 8th (last day) but I dont 'know if I want to risk wounding a deer, plus, I dont' know how hard it will be to bowhunt this late in the season right after gun season.
As far as the DL, the guy at the bow shop said it looked good. I am going to get a shorter release to help even more. He did recommend not putting a loop on the string but I really wanted one because it was a new string and I didn't want to ruin it. He fixed one up pretty short for me. All in all they were really helpful and nice and hardly charged me anything. the only thing I was charged for was the string.
