It is very difficult to get good POC anymore. Good, tight, straight grained POC is pretty tough--not as tough as aluminum or carbon, but keep them in the target and they last a long time.

Spruce is probably going the closest to POC as far as weight goes. Douglas Fir is generally a little heavier.

I've shot those, plus Pine (chundoo, lodgepole, etc.), laminated shafts, Maple, and Ash.

You can get good and bad in most any of them. I got some Maple shafts once that broke easier than anything I've ever shot, including POC.

The toughest shaft I ever shot was Ash, but they wouldn't stay straight for anything. They had been heat-straightened and sealed. Shoot, straighten, repeat. That was my experience with hardwood shafting in general.

Like Bernie said, you'll need more info. to choose the right spine. I had to go up a spine group or two with hardwood vs. POC, Spruce, Doug Fir, etc.
