I’m sure I might know a few of those peeps!
My only advice with whatever you buy is learn to fly the thing properly out of the buggy first and don’t start out in strong gusty winds.
People will recommend all sorts of different kites and personally I favoured the ozone flows as they are very forgiving when you **** it up (you will) and yet pull like a train when you know how to handle them.
There are all sorts of makes such as ozone, flexifoil, pkd, Peter Lynn etc and their beginners kites are all excellent but don’t be tempted to buy a second hand race kite off the Internet just because it’s cheap. I did and nearly ended up halfway to holland by the time I stopped getting dragged all over the place. 😀
That said, it is great fun and one hell of a rush, just can be a little frustrating chasing round for the right winds, tides etc….
