I would start by determining if the shaft is too stiff or too weak.I start by cutting the feathers off one of your arrows.You can also move your nock point up above 5/8″ above square.This will normally give you a slightly nock high arrow and sometimes makes your release a little more forgiving.Now you can start bareshaft testing,this works best with a soft foam target.Start at 15 yards and shoot a couple of arrows.In most cases if you have nock left arrows(weak spine),nock right arrows(too stiff).This will give you a good starting point.If your arrows are too weak you can cut a little at a time off your arrow or decrease point weight.Too stiff add more point weight.Hope this helps.

By looking at the paper tear you should be able to see if you have a spine or nock point issue. One of the things I like about paper tuning is that the fletching can stay on the arrow.
