I have been shooting wood for years, almost exclusively cedars. I have never had trouble with them as far as keeping them straight, and I have arrows that have been stump shooting for hundreds, if not thousands, of times.
I am in the process of working up some chundoo (lodgepole pine) shafts that I got through TG classifieds. They look like great shafts, and are supposed to be tougher than cedar, so I will soon find out.
I have no plans to shoot anything but wood; they work, and have been taking game for thousands of years.
Carbons are no doubt more consistent than wood, but for the real world in hunting conditions, wood will get the job done time after time.
As far as arrowsmiths, I do my own, but I know when I was in the Raptor Archery shop a couple of years ago, he had some really nice arrows made up, and just last week I was in Rocky Mt. Specialties in Denver, and they make some fine looking woodies, too.
