Rock West is awesome. They have everything related to carbon fiber tubing. In fact they have so much stuff I wouldn't know where to start if I wanted to buy something for, say, a backpack frame.
That's where Lawson can find a niche, in my opinion. He could carry only tubing that he has found works for a frame, tent, etc. or, alternatively, give a link to a specific product sold by others that would work for a specific application. Linking people to Fibraplex, for example, (small fee goes to Lawson) would take care of most people's tent pole needs
On a related note, I'm used to buying carbon fiber tubing in the under $5 per 32" lengths as I find it on sale at varous places (e.g. Kites and Fun Things). The prices I see at Rock West would take the fun out of experimenting with the stuff for me. Don't you find those prices a bit high?
