Rangeball,
It will be easier to determine left and rightnocks or up or down nocks if you are shooting at a rigid target like styrofoam. What you see from your shooting position will be determined by your own eye and therefore will be subjective. I try to give advice that others can duplicate. I don't measure tiller with a ruler. I do count turns on the limb bolt top and bottom and call it even enough to start tuning. There is always room for improvement unless every shot results in a "Robinhooded" shaft! I do post more detailed bowtuning information than most people. I change my own strings and cables and the relationship between tiller and nocking point adjustments does exist. I find that life is easier when I can adjust things with a wrench then when I use pliers. The Easton tuning guide shows one way, I use another, but both will work. I believe in using an experimental method that can be replicated. It has worked on my last dozen bows. If someone else wants to use an obsenely high nocking position they will probably have to adjust their tiller differently in order to get the bow to shoot straight. My experience with the whisker biscuit has been that even tillered bows will shoot real well with the arrow nocked at 90degrees. My own hunting arrows are Beman 340s, 31"long with 125 Magnus heads and they are fletched with three straight 3" feathers. The old style biscuit was not wearing the fletching. The new B-2 biscuits are softer than the old ones. The brown fibers are .007" in diameter and the black fibers are .010" in diameter. Even though there are probably more bristles in the new biscuit it shoots faster than the older biscuit. I'm not privy to what the new bristles are made of but I think they are of a different blend of material then the old ones. Hope this helped someone. Good luck hunting!
