I cannot answer your specific questions, but there was one of these skis at Gorge Downwind Champs last week. It was the only spec ski design there, though it is not to specifications—way lighter than 39+ lb requirement. I always thought a light spec design with rocker, relatively short 19’, and nose to help prevent pearling was a good idea for short period, steep Gorge waves. The trend for ocean skis at Gorge is shorter/more rocker—features specs have.
I think that ski did fine (beat me).
As a general rule, spec ski designs are not great for flat water, long distance. Might do fine in confused chop, if not too tippy, but really meant for surfing waves.
