When you're tillering a R/D you want that whip tillered look. The last part of your wood past the outer curve remains stiff and shouldn't break over till full draw. But, there is a fine line you have to maintain so the tips do not break over too much. You are not after an elliptical tiller but more of a "D" shape starting out of the fades, where everything breaks over and lines up at Full Draw, that is while you have to be carefull with removing too much wood at the Fades. That bow looks fast and smooth to me, excellent job.
