I have both the X2 gen2 and a WB3.
WB3 is light, turns very sharp, if you let off the gas it will bail you out. The stock ski is reliable, its sluggish off the line due to huge amount of water entering the w/b. I ride it flat and in waves, jumps real nice off a bigger wake. Bumping comression justa tad, and fisxing those crappy carbs a bit makes a big difference in performance. It's also relatively good on gas if you ride normally, if you ride it like it should be its gets hungry for both oil and gas - get rid off the oil container and go premix..
X2 g2 is a totally different machine and its great. It's amazing TBH, even stockish... which mine is already not...
