Can you go take it for a demo? On my 08 the goofy side stock wave was very good (at least from my perspective) The regular side was easily surf-able with stock ballast but the pocket was short. I did not mess with sacs much either.
Funny that on any promo boat videos there is no radical riding on wakesurf?!? No powerturns, airs, grabs, shuvits, 360,720 ... etc just plain riding. They probably dont know what`s going on now in wakesurfing.
