Pat, I dried a piece in the oven and checked the sg, looks to be about .75 so similar to hickory, really a beautiful wood, every growth ring is a different color, I roughed out a bow sopping wet just so I could get one tested out soon. Hopefully dry in a few weeks. If you look on the internet it does list porda carpus a a yew relative as opposed to convergent evolution. It does have a lot of similarities the wood color not being one of them. This is my first big haul of raw staves so I am excited and hopeful for it. Steve
