I have the 999 but newer tried 899, 799 or 699.
I am 76kg, my board is Alien 120.
Last year at the expo at silvaplana the boss of SAB told me there will be a big 999 and it is good for windfoiling. As soon as it was available i ordered one. At this time it was listet for windfoiling. Do not know why this is gone.
It works great for me and some other friends. I have tested it with stab 450, lift is huge. I like it more with a -1 degree shim to reduce the lift. With the stab 483 it is fine without shim. It is amazing how long it keeps flying.
I was really surprised about the windrange. Biggest sail was the 6.5 gator, smallest 4.8 foilfreek. At very low wind i find the upwind ability is not so good. Maybe because of the flat wingtips.
It jibes well, but you have to put more weight to the rail of the board as i was used with the 950. Surprisingly it does not have too much front foot pressure as expected.
