Cloud9 FS Series Review
Tested: FS 850, FS 1150 and a larger, thinner FS size
Pros
- True surf/high-aspect hybrid: lift at low speed with good glide
- Stiff one-piece wing and fuselage with direct feel
- Tail position tunes stability from locked-in to loose
- FS850 works as a one-wing quiver
Cons
- Not the best high-aspect or the best surf wing
- Newer, thinner size drops off abruptly at low speed
- Smallest sizes are unforgiving for less precise pumpers
Verdict: Playful, versatile prone wings; two sizes cover one-foot to overhead surf.
