Coming from outrigger canoeing, where the paddle means a lot, I can safely say that sup is a totally different experience with a quality blade...most demo sessions I would imagine involve indestructable aluminium shafts, clunky, large blade faces etc...if you like sup using one of these beasts, it is at least 50% better with a decent paddle. I am lucky enough to be coming into a Kialoa Kole soon, but at $530rrp they are not cheap...Xylo Blades in Qld make quality timber paddles and may be worth a look too ($320)...
