I would agree with you there southern.
Though if I had to pick a shaft, I would tell you ash is, or atleast has been for me, the most durable shaft. I have to admit here, I shot ash for a lot of years before going back to cedar. I would also bet not only the impact, but the grain structure of the shaft itself will lend to a more durable arrow then one that runs off. The more run off the more inclined it is to break. Sitka Spruce was suprisingly good compared to cedar. I have shot some maple and didnt like them. Lots of options here.
It's a shame silent pond shafts shut his doors. Mike made some awesome arrows! Was always willing to help, teach, and a joy to talk too. Not quite like some of the other arrow makers in the industry where you'd think they were dealing with aliens and spaceships!!!
