DC,, I have the same experience, if my tiller is even or negative,, it hits my hand or I have to raise the nocking point to compensate,, that being said,, if its a character bow and difficult to judge the braced tiller, if I shoot it and its hitting me,, then I make the tiller more positive to get good arrow flight with a reasonable nocking point,, I have also found that the shorter the bow ,, the more critial or sensative tiller the bow shooting well, I have had bows with negative tiller that were longer,, and they dont seem to mind so much or at all,, but the shorter ones have to have the right amount of positive tiller to get the arrow come off the bow smooth for me,,even if the tiller looks right ,, but the bow the arrow is hitting my hand,, I know I have some adjustment to do,,,
