I think we are losing track of the thread here, a bit. Longboard style SUP.
To me it has to be 10' long minimum, it has to be able to trim well, ie very little rocker. A bit of weight works well too, to provide momentum through the flat sections and iron out the bumps, when you are near the nose. Also a nose rider specific single fin. Either a hatchet, dolphin or even better a fatboy style. At least 9" preferably 10". Very few of the sups around, ride as good, as a good longboard, particularly if you want to nose ride well.
I'm am really interested to have a ride on the Jimmy Lewis Black and Blue. Only problem around here, here are no demo's available, but they really look the best I've seen (only from video's).
