Waka.. There is good and bad things about the wood shafts imo.. There's no doubt that they look great.
They flex (some of them) but I don't think they have the same springy feel that some carbon paddles have and they are more likely to break.. (again imo)..

Scotty has been using a wood paddle that has a beefy stiff shaft but a long flexy blade.. He liked that heaps.
I like the very thin shafts of the Kialoa's and I can't imagine having a wood paddle shaft that's that thin and as strong or as light.
It will be interesting to hear how Stoneaxe's new wood paddle is (the one that he won).
I've also heard great things about BoardBumps wood paddles but not used one myself.
