That rose wood looks a lot like goncalo alves. Nice to work with wood that pretty and not have the head aches that come with a wood like alves. You should get some very nice risers and tips out of that. I know I said im done with the staves for a while, but I just cant help myself. Ive got a nice ipe bow going right now. It will be bamboo, osage with an ipe belly. Should make a fast bow. After this one, im going to start back with the lam bows.
