I have two string follow bows by David Miller Longbow and a glass bow with backset. It is hard to compare them because they are different lengths and weights. One all bamboo is straight and developed a little string follow. The concave-convex all bamboo has a backing and was built with more string follow. The second is faster, almost like a glass bow. Both are smooth, quiet and accurate. The weights are different on all three. The glass is as fast as any longbow, smooth, quiet, and accurate but feels different. I was told he liked the all bamboo, or yew, but recognized the greater speed and durability of the glass bows. You can see pictures on his website, and pictures of bows owned by Hill on a link, by going to his website and then to Contact. The two Hill bows are part of John Lee's collection.
