I used the 18 F-One.After three days, the main zipper of the bag was broken and the rubber inside the safetyline, so it extended about
2m. Anyway, meanwhile I know how to relaunch the kite from water, at least if I'm not swimming.It is difficult.
In the lower windrange it does tend to stall.
But in its normal windrange, it is a rocket.
Upwind is much better than the Toro.
Could compare it with an 17ARX.
