I don't have any advice, but I just thought I'd say hello. I'm in the same situation as you. Early last week I picked up a couple of $3 parafoils for the kids at the supermarket checkout counter, and now I find myself ordering kites on the internet and wondering if I can kite surf on vacation this year. My kids, 3 and 5 years old, wander off to the playground while I fly an old stunt kite that belongs to their mom.
I have two good parafoils for them and a Prism Stylus for me coming by UPS today. I hope they will enjoy flying kites that actually fly -- the cheap parafoils didn't work at all.
I'm looking at some Premier QuadTrac Pro Foils that are on sale. I'd like to have a power kite I could fly in the park or use as a traction engine if I decided to get into that. But I should probably learn to fly the dual line kites first.
We live down in Santa Fe, so we're practically neighbors. We also have the same problem with gusty, unpredictable winds. I wonder if it is the presence of mountains.
Anyway, I hope you have a good time.
