It looks like the tiller is heavy but from what I can see the drawn profile looks right. How does it shoot? Bear tillered tons of bows at plus 1/2 inch and even more and no one had a problem shooting them. sometimes it is a matter of how high the shelf is above the true center of the bow that determines how the bowyer tillers the bow. I really do like the drawn profile though and I bet that is a smooth pulling bow.
