Hey Marc,
Beautiful bow! I'm always impressed by the perfect, elegant curve in your full-draw pics. Just lovely!
I'd never heard of "Santos" Rosewood before, so I looked it up on some wood distributer websites. Come to find out, Santos is a regional term, that some use to refer to the more commonly known Bolivian Rosewood–which is not actually a rosewood at all. After true rosewoods were over-harvested, endangered/protected/outlawed, some other similar dark, tropical hardwoods took their place, with new "rosewood" names, to fill the commercial void.
Santos & Bolivian Rosewood are both synonyms for Pau Ferro.
*I am by no means an expert on tropical hardwoods, so anyone, feel free to correct me here. I only put forward this information to aid others in their search, should they decide to go looking for some of that wood.
