I think if you have gotten past the getting upwind stage, then you could be ready for this kite. Its a very easy to fly and handle, the only difference is it likes lots of board speed (apparent wind) to fly well. This isn't always the greatest in big chop, or on bigger boards, so you have to consider that when making your decision.
If you don't want to be a speedster all day, then consider a 11m Yarga... I think it would make an excellent Gorge kite. The 13.5m is a great kite, but it just is too grunty for me most days in the Gorge (170lbs on a 132cm board.)
For Sauvies, the 16m or 18m Nemesis would be great choices. I like the 16m and actually find myself very juiced up on it even when its not that windy.
thankx so much for your comments. Very helpful!! Basicly, I'm almost in the same situation. Just started kite-surfing yet with the pre-experience of kite-boarding in the meadow. Going with a 9.5 Ozone Frenzy and Libre Mountain-board. Really helped me quite a lot so as to be able to go properly upwind on the first day of the course with a 12sqm wing at 26 km/h; board 150cm/50cm width. Drove me all crazy, so I need the equipment as it seems to be even more fun on (or rather in the water esp. when it comes to turn around which I cannot really do yet; tried it with flying turns, but the landings are still a bit harsh'n ' bumpy.)
Anyway, I'm about to buy the best offer, which is buy 2 get one free. Just saw it on the internet yesterday. Beforehand I thought about buying only two kites (Slingshot Fuel or Cabrinha Co2; approx. 12sqm and 16sqm)
I don't know your spots as I go kite surfing in Holland (either waste deep water for the next couple of weeks, so less choppy conditions, but I also wanna go during the winter on the cost where it can get fairly choppy...
Have you got any recommendations which 3 kites to buy in the range of best or cabarethe kites so as to cover a good wind range?
Can I mix up mid AR and high AR, e.g. yarga and nemises? I also don't wanna grow out of the kite that quickly...
And as regrads the sizes: Which size would ya recommend for let's say the nemisis and which for the yarga?
My weight 75kg, board: I immediately bought the one I was able to go upwind during the course, so 150/50cm.
Sorry, if I'm waffling around. It's just that I#m fairly new into the whole kiting business and I just wanted to make myself as clear as possible.
Thankx in advance for any answers.
