Nice pictorial, Mickey. I didn't know if anyone knew, but there are only 2 bamboos(canes) native to the US and both are call river(switch) cane. Arundaneria tecta(average height 5" with a fairly thick wall and small pith) and Arundaneria gigantia(to 10'+ with thin walls and larger diameter pith). Either make good arrows.
Anyone that has read The Witchery of Archery will remember talk about cane breaks that took days to cross.
Today there are other "canes" around that will make good arrows. Mickey, Have you tried the "bambusa"(?) I sent you. I've made a few arrows with it and it's nice to work with.
A little secret I learned with cane. If you use the heavy(spined) side for your cock feather, and leave some extra length, heavy spine canes shoot great from most bows.If you have a cane that shoots differently than others, flip it and shoot it with the cock feather in. Thanks Mick. With the price of shafts coming up, cane and shoots are gonna be sought after. Pat
