I just tried a 10m Nitro V2 the other day, and another buddy of mine was on his 12 SB, and I was on the Nitro, He had issues staying upwind, I had no problem @ all, and I'm a bit heavier. I ride the Method 12 and 9, and I really, really enjoy how they perform. But I would've not being able to stay upwind on my 12m Method as I did on this kite, and I was staying upwind no problem with the 10m V2, very powerful, and quick, but not quick enough, the Method is explosive fast, you think of turning and bam is there, it just feels perfect.
It had a great boost, but so does the Method, but the Nitro glides sweet. You kinda drop out of the sky with the Method, Nitro this is a jumping machine.
So, for waves? mmmm, not sure, it felt a bit slow for the surf, surf was low the day I took it out so not sure ow it performs, and it was about 14-16 kts, cross on. Bar Pressure was perfect, where as the Methods is a bit much.
Hope this helps, if you can demo them, I feel the NV2 is more of a freeride booster.
p.s. I hated the Element, its low end sucked (for me), I hated how light the par pressure, I couldn't feel where the kite was, love how it turned, and I've heard is great for unhooking.
