I bought this board last month, and am very happy with it. Some quick notes to share:
-I weigh 165 lbs @ 5'11". I'm sailing the board with a 5.0 and smaller sails. I am efficient but not extremely so, and have been surprised with how easily the 77 liters carries the 5.0. The board is replacing an 84 liter Naish Wave...if anything it planes earlier.
-I was on the fence about FreeWave or AllWave, and went Freewave because I do a lot of bump sailing (and thought I'd give up a little turnyness for a bit more speed.) This board is far more nimble than my old waveboard...I have no regrets re slashyness in the waves.
FYI
