My 2nd hand 06 Ezzy SE came with a keyring. I'm playing with it right now making "pschhhhew" water/wind sounds.
I've had one, just one ride on it so far, and to be fair I'm pretty crap and I've only sailed 3 or 4 other sails, ever. I usually sail an old 6.4 KA Kult.
But here are my first opinions, for what they are worth.
Very gusty conditions - dead calm to 32
1. Stable - cut through gusts like they were made of air.
2. Smooth - I'd describe it as "very smooth", my old sail as "crisp" in comparison. Actually when combined with the carve it's all getting a bit limosine smooth.
3. Big wind range - not sure at what point I got planing on a 111 carve. Didn't feel much diff than on the old KA Kult. However, the sail seemed fine up to those 30 knot gusts, which is not bad for a 6.5? Gusts went, somewhere.
4. Tough - You know you shouldn't, you know you're on the edge of your skill range, but you do anyway. You point her way off the wind, just to see how fast... SLAM! My mast base connector was no longer connected to the mast base, my spreader bar was bent 90 degrees, i was trapped under the sail hooked in, and my head and neck were aching.
The sail was fine. I'm pretty sure I hit it hard, but is a bit of a blur.
Anyway, it will be interesting to see how it goes in marginal conditions. It does have a lot of shape to it. I think it actually has a lot of grunt but is a bit heavy.
That said nobody planes as early as haircut

, he seems to get going in 10-12 on a 5.8 when otheres are rigging 7.5s. Mind you he's on a freestyle board. You tell me.
