I have a fish 5-6. I'm 6-1, 230, behind a SANTE 220. We run belly and port stern tanks full, plus a fatsac at each location. The wake is hip high on me.
I can almost free-ride the fish. One girl has been able to free-ride (she's about 115) and one guy at 165. I can almost do it, but it won't quite keep up. Not saying I'm the most skilled rider, def a rank beginner, but I don't think this board is worth the $. It's fine to learn/teach, as EVERYONE gets up in 1-2 tries, but it gets boring, quick!
