I paddled the 9.3 C4SV in some choppy surgy cr*p a few weeks back at Mona Vale(thx again Simon and Stuart).It is alot more stable and punches through the whitewater nicely cf the 9.6WAA that I own (and love btw).It also had slightly better glide.Pretty thick boxy rails though or maybe it just looks that way on a shortish board with a sunken deck but that's the whole point of the design.
Nose rocker means late is ok also.
At 6'3 and 100kgs it felt a little too short for what I do and the 9.6 or 10 sv would suit better.
Hard to imagine anything going as well as my PSH in clean conditions though.It somehow turns kook into kool(ish)

.
My summary: great intermediate + board for a big fella.
