As someone that was part of the 'Paddle Talk', I ended up purchasing a Black Project Hydro 88 on a Medium shaft. Chris from BP sent me an email suggesting that a stiff shaft would suit me better as the length of the shaft, I'm also 6'4", would have overly too much flex if I went with the medium. I'm still waiting its arrival, and have never used it, but all things considered, I'm stoked!

Could be worth your looking into.
