If You haven't already, Like Mr Hoppe mentioned, I would suggest asking Chris. I've bought them from Him before when in a pinch in the past. Sometimes He has shafts like that in limited numbers, and will help out. Cost You a little more then sourcing, and turning them from scratch, but he's honest on grading, and is still fair on price considering what they are, some of the work has been done, and considering what You can get per shaft, It's well worth It IMO. I've never had a shaft that I got from him move on me either. I actually just picked up a couple of purple heart shafts from him. I was out, and have a customer that wants me to build him a break shaft like I made for My personal break stick. They are already at around 16mm, so I should be able to bring them to size a lot quicker then I would have otherwise.
