"The wider span, enhanced profile, new rigid wing-tip design and ASS all work together to bring you a super quick turning, ultra powerful kite that flies incredibly fast through the window. Upwind ability is unmatched, in fact a 16m BFK with ASS has the power of most other brands' 20 meter kites with the perceived agility and turning speed of a 12-13m kite."
Maybe we can get a demo kite here to try out on those light wind days, who knows?
Blair I think it flattens out the kite to increase surface area. The wind wings do the same but not so extream. I'm going with the wind wings. best makes a good kite but, I think the SAFE system is the way to go. They claim you could use it in 4knots. I want to see that
In all fairness, there's a certain amount of hype and propaganda to be had with all kites. Cabrinha Contra press: "Targeting the light wind threshold of 5-10 knots, the Contra was developed specifically to produce power and true light wind performance when you need it the most." Same thing, 5 knots will get you nowhere.
Hype abounds all the time ... Looking at the new Naish Torch ads, while I'm sure they are indeed rockin' kites, they'd have you believe that nothing like it has existed in the world up to now. Who knows, Windwing might be even have their share too. I'd still like to check them out though.
