The more I think about it, the more I think I just need to weaken the top limb some more. With my boo-boo on locating the hinge, I have my shelf over two inches above center. That is the highest I've ever located it. By theory, it should require more positive tiller than my normal +1/8-3/16". I think I can bring her around with the proper tiller. If the limb tips look mis-timed, but it shoots better, I'm ok with that.
