Ok. I struggled with that shorter draw length. I find that in order to get the string back to my face I need to bend my bow arm more. I also come to another conclusion. Without holding a bow I naturally stand leaning a bit that same direction. A number of factors are at work here. First, nobody's back is perfectly straight, we all have one leg longer than the other. Albeit these variations are usually slight. To further complicate things I have a lifetime of wrecks. Bicycle wrecks, snowmobile, motor cycle, horse, falling from roof of the house, all of these wrecks have taken their toll on my back. It's actually a wonder I'm still walking. So no small wonder I'm a little off kilter.
All that to say I have put 1/2" back into draw length. Now at 27-1/2" DL. At 70" wingspan that calculates to 28” DL using the wingspan over 2.5 formula. I'm going to try this DL for a while. I find so far though that I tire out sooner with this shorter DL.
The suggested adjustments to nock height and arrow rest height have made a big difference. Bare shafts are flying straight and landing the same as fletched arrows. My limb bolts are back to being even. I'm a little confused by this though as having the arrow so un-square from the bow string goes against what I read from Nuts and Bolts.
