you were at Waukegan on Friday, flying a Naish Arrow... Yellow / Black and White.
You will have more fun with that kite if you get longer lines. I may even have an older (but unused) 27 M 4 line set that I'll sell CHEAP! For some reason, when they made that kite, there was a "surf" craze and everyone wanted shorter lines for faster turning kites. However, it really didn't do too well on a 20 M kite.
The kite has a short range of power/ depower, and over sheets easily wit hthe setup you've got.
If you mess around with a new set of longer lines, and maybe do a 5 line conversion I think you'll have a better experience.
Just my 2 cents worth.
