the best shafts I've had so far are the poplar dowels at lowes and HD. My sitka spruce shafts are snapping all over the place, POC also stands for "piece of crap", and the oak I've tried makes me too nervious to shoot off my nuckle. I can't find any decent bamboo there,... I'd like to try shoots if I could find any around here. Until then, I self spine the poplar dowels from the bin and they usually shoot pretty good. The only time I've ever broken one was when I shot the nock off, and I was too happy about it to feel bad.
