First, and this is just my uncharitable opinion, but that guy in the video is a classic case of someone who would benefit far more from the stable platform of a hybrid than try to surf a classic shortboard.
Scott, I surf the 6'4" Dom and 6'8" Alt. I really don't notice the volume difference between the two, and in any event you want a tad more volume for smaller days - that or more surface area (or both).
I agree either a Spit or EF would both work with those waves but I personally think a Spit is likely to be a more versatile board. The EF has a VERY flat rocker, which makes it fast, but less forgiving.
