Superfreak
I have never ridden anything I like more than my freak. It does EVERYTHING so well. I like it for just cruising around.......I LOVE it in the surf.......It's great for hood tricks.......it's great for flatwater rolls and flips.......it just does everything so well. Like Matt E said.......it is more work to assemble than some of the other options, but worth it in my opinion. I don't even have a single stress crack in my paint yet. Tem certainly knows what he's doing and is a great guy to work with. He will build you a ski to your specs and do it in a timely manor. EVERY single person that has ridden my ski has told me it is the best riding hull they have ever been on and they were immediately talking about ordering one.
Rickter
I have spent considerable time on FS1's and FR2's on both flat water and in the surf. I think the Rickter is a very good surf boat. I would rather ride a superjet on flat water though. The XFS might be a different story.....I haven 't ridden one, but guys seem to like them in both surf and flat water.
Waterdawg
I am not a ROK fan. I spent a couple hours on one and just didn't like it. I felt it was nose high and rode bouncy. I also couldn't get the thing to carve to save my life. I realize this could be partly set up, but we made a number of adjustments and I still didn't like it.
I actually expected to like the ROK because I had ridden Madmat's Envy at Waverave one year and really liked it. The envy might not be the ultimate flat water ski, but it certainly felt like a great rec. boat.
BOB
I have not ridden them so I will not speak to how they ride. I love how so many people on these board act like an expert about something they have never spent any time on. Talking to people I have heard that the Gen2 is a whole different ski than the Gen1. Certainly the price is good which should make them worth looking at and test riding.
Watercraft Factory
I have not ridden the Vision yet. It's a cool looking hull and Steve seems like a good guy. I was very happy with the hood I bought from him years ago.
I really haven't ridden much from Trinity or EME so I have no right to an opinion.
