Definatly another reccomendation for Mike at The Nocking Point. Great guy and place.
I like Sitka Spruce and POC both. I personally find wood to be much easier to tune than carbon. You can change points without having to match all the components such as inserts and whatnot. When you get close, just start trimming the shaft a little bit at a time untill you got em flying well. Wood is, in my opinion, but less OVERALL hassle than carbon, because you don't have to have as much stuff to work on them. Add to that the asthetic value, and wood wins hands down. I too have some Gold Tips left that I am going to keep shooting till they are chewed up, but only from one of my bows. After that, I'm even gonna use wood in that recurve. All my selfbows already get wood. It's really a fun - and plenty functional - material.
