moving-water test required!
I'm 6' and 140#, w/ a 32" inseam - pretty much the same size/shape you are.
I'm in an EZ now, and want out... it's not responsive enough.
Last week at NOC I demo'd both the LiquidLogic CR125, and the RX6.7.
What I found was the CR125 felt better sitting on a flat, but was MUCH harder to surf under control. It wanted to carve no matter what I did, and pushed itself backward off the wave at Surfing Rapid on the Nantahala, repeatedly (about 30-40 tries). The next day I demo'd an RX6.7 at the same place.
I was able to get onto the wave on the first try, and sit happy. One of the instruction-staff there described it by saying, "LiquidLogic boats want to be vertical - Dagger boats want to be horizontal." I don't know if that's true, or fair, but the Dagger boat sure was better for me.
I'm primarily a river-runner, with occasional surfing and spins - hardly any (intentional) vertical moves.
Hope this helps.
