Yurkanip has it right - ride as many as you can. I love my Q8, but there are a lot of people who really don't like riding them. Rickters feel like SJ's to me, but just "better". Rode one BOB gen 1, had a hard time riding that one, but some of the other guys just love them. It's all rider preference. If you are ever in the Scottsdale area, you can take my ski out for a tank of fuel and see what you think. One of my riding buds has a FR2 Rickter, he's not as into sharing his ride though.... and another has a seriously chopped up SN that is a blast to ride. The Epic Industries hull is a pretty fun boat, but it is an entirely different feel than any other stand up I've been on - the handling is very different.
If I was to do it all over again, I might give my money to Tom21 for a carbon FX1 hull.... but I'd have to test ride one first!
