Will, and I are good friends. He came over my place today,and shot the bow through a chrony with a heavy Dacron string, and wanted to increase the speed of the bow. I tied him a 10 strand D97 string , and the bow increased speed by 11 fps.He went home a happy man. I also gave him an Elm stave. He gave me some sinew,and not long ago a copper head snake skin,and an Osage split stave that was iffy. It is finished ,and I will post it soon.
