I must be lucky; I have never had a snaky bow fail. I have one out there that probably has 100K arrows through it and is still shooting, others disappeared around the country and I don't know where they are now. When I make a snake bow, the new owner wants one with all the bells and whistles which includes snake skins, tip overlays and burl wood inlays in the sight window. I suspect these bows are babied somewhat and not everyday shooters. With that said, I never made a snake bow with wide sweeping curves like Arvin's project, my bows all had tighter snakes.
I did notice the other day that an old friend from long ago used one I made about 20 years ago to win the primitive class in the Bama state championship this year. Someone had take a picture of Tim out on the course and I noticed that he was still shooting the bow that I auctioned off to raise money for the Alabama Children's Hospital. His bid was so generous that I made a freebie BBO for his wife as a thank-you for his bid.
I put an inlayed a burl wood name plate in each of the bows, this was in the BBO.
