western red is very brittle.
fir is awesome. tough, heavier- little toughter to cut through the dowel maker. most d. fir sold is second growth- which is a bit softer, but still ok.
i love sitka spruce too. really resilient, straight, hold their shape well.
you can run your arrows through a compression block- that will smooth them, and reduce o.d. BUT will also reduce the spine.- and will be a bit resistant to stain after compression
3 rivers sells em, in different sizes.
or you can make your own- real easy.
pm me if ya want some sitka, or how to make the block.
best regards
