well, im riding a compression broadcast 5'6 with 300 pounds of people on it, the only people on the boat sitting on the side im surfing are kids and a retard. the driver weights about 400lbs with 2 adults sitting behind him.
factory fill and 2 old v drive sacs in the rear and port locker plus factory surf setting, I think the center ballast was changed to empty and slowed down .2 from the stock setting.
long story short, even with a completely bogus setup and people arrangement I was riding ropeless with the hardest board to ride ropeless with a kid on my shoulders.
taking it to my dealer next week to plumb the proper bags and will report back.
