jedi: very similiar situation to you recently. Got given a stacker 6 - then it was pinched within weeks (along with my sound system!).
as I was hooked instantly, I went and bought a Super 10 two weeks ago. Since then, it was only this last weekend that we have had any decent wind (S Wales). In the meantime, a couple of really nice kiters whom I met on the beach gave me a go on:-
Slingshot (dont know the name - v small) - it was awesome - pulled my 13stone in a very light breeze. I have heard bad things about this kite, but I thought it was wicked.
Ozone - WOW - very stable and a very nice constant power.
Razor - SHEESH -I wish I could afford one. Took me 150 meters within seconds. Probably something for down the line...
Blade II 4.9 - I bit of a letdown after all the hype from my research. Only because it was more difficult to turn than I imagined. Having said that, I am a (fast learning) beginner. And I am saving up for...A Blade 4.9 !!!
My advice - pick up a cheap super 10 or Proteam 8 second hand- both great fun - but be prepared to be bored quickly as soon as someone gives you a go of their traction kite whilst out on a lovely summer's day !
