great advice guys.
i called into a local kite supplier (by pure luck based where i live and found it on the flexifoil site). he recommended the blade 4m and said it should give me the range i need to start with. i hope he's right because as you say it's an expensive business at 330 bucks.
the little devil looks interesting and seems cheaper. anybody got one of those. whatever, i'm now itching to get out there and have some fun!
