If you're getting a custom bow made, and know you'll like it/keep it, order some of the most exotic stuff you can. Another $100 in woods and you'll love your bow even more. Clal the bowyer and see if he has a special piece lying around or somehting.
Me ?
I like bocote ... love the stuff.
Got to
www.blacktailbows.com and click on all those bows to get an idea of how woods go together great photos of how exptic woods should look
