So I made a bow yesterday out of some Pennsylvania yew. It's made from about a 3" diameter branch, 58" ntn and pulling about 53#@28" Pretty neat, it has sapwood on both sides of the grip. 1 1/2" wide from the fades for 10" and then tapering straight to 1/2" tips. I didn't reduce the sapwood at all, just used the first ring under the bark. It started out with about 3" of natural reflex and finshed out with about 1 1/2" all and all I'm pretty impressed with this wood, as I wasnt expecting much after reading some peoples reviews of low density yew.
