I agree that white cedar (thuya occidentalis) would be good for arrows only but tamarack ( Larix laricina) was used by natives around where I live. I have a hunting partner that told me he was given a tamarack bow made by an Abitibi region native. Also in TBB4 tim baker states that good bows have been reported. I say go for Tamarack, long and wide bow will prolly work.
