I harvested some bamboo shoots(Fargesia scabrida) that I have been growing for a couple of years. So far they look real good as far as weight and spine, between 350 and 400 grains and 45-70# spine. A few of them have quite a lot of taper from 3/8" to a bit less than 5/16". Is there such a thing as too much taper? What problems might it cause?
