Tips look better! I think the suggestions so far are good. Do you have a tillering gizmo? If not, a straightedge (eight inches or so, or even a 12" combination square or ruler) can serve the same purpose. Run whichever of those you are using along the belly and look for even spacing to show what is bending and how much. Mark spots with less space between the straightedge and belly, and take off wood there. Stay away from the center for now, and don't get carried away with the tips - the last few inches shouldn't bend as much as the rest of the limb. Hope that makes sense.
