I know laminated birch sahfts are popular and i have read that birch shafts are tough but tend to warp. i was wondering what your experiences are with solid 5/16 birch shafts, not laminated. Does anyone have experience with 5/16 birch as far as getting enough spine for hunting weight bows? thanks, Dan.
Never tried 5/16-inch birch. I need about 70-75# of spine, and 5/16 in birch just doesn't make it. Have shot 11/32 birch, plain and laminated. For me, the laminated was more crooked to begin with, and needed more restraightening to keep straight than plain birch. Weights are about the same. I do like birch for a heavy arrow, though. Ash is very similar. Maple and Hickory are even heavier.
