Which wood should I choose for primitive arrows with stone points? The points range from 92gr up to 125gr. I shoot a 47lb long Rf/Df long bow. I was looking at ash or sitka spruce.

Ash would be the tougher of the two and the heaviest. Why not go with natural hardwood shoots like red osier dogwood, silky dogwood, youpon holly, privet, salt cedar or one of the canes like river cane, switch cane, Jap arrow bamboo, Tonkin cane or even Martha Stewart's bamboo plant stakes(Tonkin).
If you are going to make a primitive arrow, make a primitive arrow! d;^)

I agree, use a natural shaft. Far better mojo and coolness points.

What they said.

Ryan, I just made some using bamboo. You can see them on page 2 of powwow under arrows and feathers.

If you looking to buy shafts, I would choose the spruce or fir.

If your going "all natural", I would go with rivercane. You should have it in Texas!
