I was moving over to all woods years back, then I was given a gross of 1918s with glue on one piece ferrules and screw on ferrules. They flew just right out of my current bows. However, it seems that the guys that I supply with arrows, \\ prefer woods. I turned over over a Schulz to a guy this week, I offered him aluminums to go with it, but he wanted woods, I turned the bow that he turned back to me, over to a kid that I gave a recurve to and he also wanted woods. So there goes my my stash of Surewoods and tapered cedars again. I was going to buy the shafts for for him, but ones that I had on hand worked just right, so I will be replacing my stash for the next bow I have coming for myself instead. That will give the freedom to use what ever spine would be best for the new bow, so I am OK with it.
