I've noticed that there are a few arrow smiths on evilbay that are selling arrows on a regular basis, and they offer a custom service as well, one of which uses Boyton Scotts Pine for the shafts.
I had thought that it would be a case of just trying out various types of wood, etc, to see what suits my bow and shooting form best
Any other help and advice is greatly appreciated, thank you everyone so far
