Bamboo fly rods were built the same way, and still are if you have enough money to afford that kind of custom work. The 'boo is split, shaped, and re-assembled with the insides now on the outside and vice versa. It makes it possible to get consistent diameter from end to end without losing strength. From personal conversation with someone that has used these shafts, I hear that they start pretty straight and rarely ever need any straightening, certainly an advantage in my book. I don't know anyone that has used the pine hex shafts, got nothing for ya there.
The solid cane shaft proponents scratch their heads and wonder why someone would take all the time and effort when the cane is naturally such a good arrow material. Find a simple answer, disseminate it to the general public, and watch every last one of us try to find a way to modify or improve on it...that's what humans do. That's why we left the trees and ventured out on our hind legs n the first place.
