It would be difficult to qualify one as being "best", but there are several who make very good wood shaft arrows. Within TradGang, I would include Bob Burton, Badger Arrow, Stu Miller, jlnft, and would like to include myself. Outside of TG, I would include Jim Curlee and Paul Jalon. There are others in both categories that I'm not thinking of at the moment or whose work I am not familiar with, such as Hot Hap. Making good arrows is not necessarily difficult, but does require dedication to the trade and serious attention to detail.
