BigBuck, Bulldog1 here, I need to know what bow, fingers or release, based on what you told me, it's sounds like your arrows are too weak, a 2314 or 2312 will do the trick. Also you said you got fletching rub when you took your bow to center, unless your bow is older, that should'nt be happening. The thing that's bothering me is your arrows should'nt be that far off between field and mechanical heads let me know. Bulldog1
