RE: fighting bow up
Though it' s hard to say without seeing you shoot, I don' t think tiller tuning would help a whole lot. I also don' t want to come right out and say Target Panic, though it' s possible. Check your draw length. If your draw is too long you could be over extending your arm, which could make it hard to bring the arm up high enough. Are you able to aim steady when not trying to aim at a target? If not, draw length could be a problem. If you' re solid when not " trying" to aim, something else might want to be checked out (possibly the dreaded TP word).
