Total flying time on the 6.5 is about 10 minutes.
Total flying time on the 2.5 is about 7 minutes.
These are good kites. There are no rips, stains, tears, etc. For all practical purposes just consider them new.
They're just not my bag, baby.
It's a windy day so I took photos inside, then folded them up and went outside in the sunlight to get a better representation of the colors.
I'd rather have a small (high wind) foil in decent condition. Have something in your closet you don't fly anymore?
