Good question,
When I used to wakeboard , I would prefer a slight ripple apposed to super glassy . I wasn't that good and I don't know why , but it felt different. I would unexpectedly crash more often . Mostly when landing a massive one foot high jump,( told you I wasn't that good )

. Maybe I was pushing harder on the glass ?
I would think a windsurfer would feel more sticky especially on a bigger board ???
