Thanks for the nice comments.
Dwardo, I'd argue that hickory likes the scallops on both sides because it essentially created a trapezoidal, "trapped", cross-section. That along with a healthy amount of heat treatment, I think maximizes the potential of hickory. I don't know if people treated bows this way for that reason in historic times, likely the scallops were more decorative or ceremonial, I'd guess. But this bow has been shot hundreds of times over 5-6 months and the wood has responded well.
I did sand in the scallops.
