Art you must have access to a lot of cane if you can be that picky with node placement. I usually get a dozen pieces of cane a year and trying to manuever node placement around tip and nock is hard enough LOL
I've shot cane with nodes just below the nock,actually in the nock, in the feathers, 1 1/2" below the tip, furrows in, furrows out, furrows up, furrows down...and anywhere from 3 to 6 nodes in a 30" span.Of course I shoot off a floppy rest so there is "give" in the shot. That and paradox means there's not much worry about node location to me.
I've only had one piece of cane that had to be shot cock feather in so I stripped the low feathers and made it a 4 fletch flu flu. That was a piece of Martha Stewart cane from the garden store.
BTW a few years ago there was an article in one of the magazines where someone found a box of Japanese cane arrow shafts and they all were perfectly straight, had 4 nodes and all the nodes lined up exactly the same on every shaft (if memory serves me). Now that is awesome!
