I have been riding old C kites for about 4 years now and just bought a new SLE , it has heaps of grunt bigger wind range and looks hot. Call me old fashioned but my old C kites are still very enjoyable to ride, I know they aren’t as safe but people seem to bag old C kites all the time.
Maybe one- day old C kites will be like classic old cars, heavy, under powered, hard to find parts, but worth more than an average mortgage! Or not.
