Personaly I can't see any arrogance in Johnny's help, he's given us loads of info on the new SS kites, take a chill pill dude, have you helped Pedro or anyone more than Johnny?
I think the wind ranges on the white reef site are pretty accurate
A mate of mine just tested the Fuel 17m and said this: 9/12 kts with a jarvis 157
low range 8/9 knots but it obviously depends how much you weigh, what board you use and how good you are in lightwind.
With the 2002 16m Fuel I can get going on a 7' directional in 8-9 but with a 170x40 TT need 10-11, I reckon the new Fuel will be about the same.
