We are talking about "ideal" here and that is something that eludes me for the most part but, I agree with bubby and George, and would add that since the left limb leaves the handle at a greater angle, and with the goal being that both limbs are equally strained at brace and full draw, shooting for that picture perfect shape may not be ideal. If both limbs are equally strained, the brace profile may look a little off and in fact that would be "ideal".
