I am not sure that I would trade my smaller F-One B6 for a Speed 4 8m but my point was that the new speed 4 behaves very good in gusty conditions:
that review pretty much sums it up:
All in all:
We really had a lot of concerns about this kite. But after today we love it and won't change it
I normally ride tubes when the wind is over 25kts. For safety reasons and because the tubes are just more rigid and stable in these conditions.
But the Speed 4 has totally showed us today that they work in higher winds. And not only 4 pros. There where some other testers that really liked the kite.
As mentioned before: Gust eater.
But also when you depower the kite it's still super stable.
Even at the beach when you land it, we normally have wing tip collapsing wight the Speed3's (cause the wind comes a bit over trees and there are wind rotors). Not with the Speed 4's at all. STABLE! As mentioned before: Gust eater.
