RE: Whats wrong with my setup?
I totaly agree with you on that point. For fixed blade heads I feel you need to be much more critical on your set up. Whether you have a lot of KE or not.
My original point was that tuning is not going to fix this guys problem. He was talking about practicing at moderate ranges and not grouping well. No amount of tuning is going to fix this kind of grouping problem. Everything I stated was aimed at target type stuff and meant for field tipped arrows with good fletching. Not shooting a fixed blade broad head.
In order to tune a bow you have to be able to first shoot it well enough to tune it. Other wise you are just wasting time and effort and will never get conclusive results. You can't expect to tune a bow better than you are actually capable of shooting.
Now if he would have said "I shoot fine with field tips, but my broad heads just won't group well for me, what is wrong?" Then maybe I would have mentioned tuning and trying to get a better spine match. Along with checking to make sure your heads spin straight when mounted. And also looking at form, since broad heads can magnify problems that you wouldn't normally see with field tipped arrows.
I just feel that people worry way to much about having the perfect tune or what sort of expensive gizmo or high tech drop a way rest they should be using. When the truth is none if it will really make them shoot better. They might for a while because they feel more confident that what they did actually made a difference. Eventually the same problems will begin to occur again though and they will look for some other excuse or quick fix or new gadget that will ensure they will shoot better. I did the same thing when I first started. That's how I know it doesn't work, I tried most of it already.
You know how I started to get better. I quit worrying about it concentrated on shooting. And when things were not going right I stopped blaming things other than myself. If yesterday my bow shot perfectly, and today I can't hit anything I don't think my rest is wrong. Why did it work yesterday when every thing was the same. Hmmm, must be me huh!
