Hey Shlomo
I'm an intermediate rider and I've got the '07 9m and 12m... It's really heavy on the bar and slow turning when set up at 2:1 (pulleys), doesn't have "full" depower when set up 1:1 but changed to the smart loop (retro fit kit for ~$120) and it is a completely different kite... "full" depower and lighter bar pressure. Good all round kite haven't flown anything else so can't give a comparison but haven't heard anything bad about them either (possibly cause I don't know anyone who flys them. I've had them since beginning and given them an absolute beating and they are still great kites.

I have a 15m and a 12m. I don't know about your local conditions - you haven't given us much to work on. I thought I needed a 15m, but my 12m is fine for the most common conditions in Melbourne. The 15m has heaps of grunt but is really slow turning. I'm going to sell my 15m when it arrives from the UK as I have ended up using it about 3 times, its still brand new. If I was going to ride in anything less than 18 knots I would consider getting a bigger board rather than a 15m kite.
my wind condition is 12-20 knots,
i'm now learning waterstart
i want to but this kite to replace my f-one 16 M6 kite
