I've got a pair of HO wake skis. They're shorter (145s?) than the sterio skis (155s?) and they've got a lot more rocker, so they're kinda squirrelly if you aren't a solid water skier, but they're fun as fuck. I ride em several times a week from april - oct/nov. (Hoping to get out tomorrow for the first time this year.)
My homie has a pair of the sterios and he loves them. He's a lot bigger dude (210 vs 150), so they're a lot more stable for him. I've heard several other people voice the same opinion.
But yeah, at any rate, wake skis are dope. Buy some. Ride as often as you can.
