BTW - over summer i tried a CB wave, Underground SRF and North X-ride.
Personally the CB wave was awesome but I would have liked the option to put straps more central.
Agree with Eppo - CB Wave's upwind ability with thruster forward was outstanding. Liked a lot about it (and SRF was decent too) but at the end of the day I still like a standard TT with a surf-ish outline and tips, with twin fins and no thruster.
I miss the ability to choose whether I want to go for a bit of mush natural or goofy with same response/tracking either direction.
Strange I know - but I kind of like pushing smaller twin fins until they are starting to break out too, the gouge/slide/recover is great fun.

Keeps it interesting.
North 136 X-ride was excellent but would have liked to try the 140 model for even better plaining on waves. North S-curve fins held very well for littlies.
