I'm in the market for a new (to me) boat. Will probably pick up something used. We mostly surf and pull kids on tubes, with some wakeboarding and slalom mixed in. Originally, I narrowed my search down to a GS22 but I'm still uneasy about what I read about the surf wave. Even with extra ballast, it seems to be just ok. Someone suggested that I take a look at the Fi23. I can't find much at all about the ability of the Fi to lay down an ok slalom wake. Really, the only thing that I have found is a Boardco video comparing the two boats. That video speaks pretty highly of the slalom wake but I'm hoping for some more feedback. Any experiences here?
