Well, after carefully considering all of the above, doing a lot of reading, and talking to a few different bowyers, I decided to order a black locust selfbow from Curt Brisky. Should have it around the middle of next month. Needless to say, the wait is driving me crazy.
Here's a fun little sub plot to this story: I'm also a musician, playing and recording Celtic music (among other things, I play the pennywhistle, thus the first part of my online nickname). About the same time I was ordering this bow, I was also ordering a new bodhran (Irish drum). The drum maker, who happens to live just a few miles away from Mr. Brisky, happened to mention that he has some beautiful black locust lying around. So, it looks like I'm going to be the only person I know who has a matching bow and bodhran set. Not that I plan on using them together, all that much. I find that wild critters in general are not music lovers.
Anyway, thanks for all the advice and help as I was figuring out what I wanted. Much appreciated. Thomas
