Give him 5 years of heavy R&D and he might catch up the big names. In the mean time I wouldn't waste my money.

I assume it's a zip-together concept which must leave the centre section with a triple layer when zipped to the small size. A lot of weight there doing nothing, must cause flying issues. Also the weight of the zips when not in use is a handicap. Also I've found zips and salt water to be a bad mix unless you spray with lanolin regularly.

He said he's been told " people would pay an extra $200 -$500 just for having the zipper on there." I wouldn't, personally I'd pay $500 for a 2nd hand kite in the second size that I wanted and have 2 kites that are optimised for that size rather that one kite that compromises and flies both sizes poorly.

My initial thoughts, I'm sure others had the opposite reaction?

way back when there used to be a kite that was two sizes in one...

a zip along the center strut turned it from a nine to an eleven and a half...

can't remember the brand, but this was back circa 2002/3

Velcro ?? thoughts

yeaaaa :) would hate that !

thinking outside box is what leads to design progression. What seems like a gimmick now may well be a standard feature in the future.

Flysurfer already have kites that can change the size of there projected area to create a massive usable wind range.

One kite and two sets of B&Ls - a long set and a shorter set = kiting in 2 different wind ranges and no zips no worries
