That looks like a great piece of yew you have. Nice ratio of sap to hartwood from my novice eye. Never shot or even seen an elb design up close before. I do like that style of nock, looking forward to seeing it all finished up. 
Putting some oil on my swap bow. I learned my phone camera stretches the image near the edges, that kinda messed me up for a few days. Made one limb look maybe 3 to 4 inches longer that the other lol.  With any luck I can get some good pictures this weekend and post. Mike
