I have the 1150 and 905 foils. They are really nice. I have the 78 mast 16mm. I have the 160 tail. Foils are fast, lots of glide and turn pretty well. Havent ridden them much. They are not difficult foils.
Tried the 1150 only once in condition where the wind was low and I wouldnt normally go out. I guess the wind was 8 to 12 knots with big holes. I had no trouble getting on foil, easy to pump through the holes and it has a very low stall speed.
One review I saw says they compare to the Enduro foils from AFS which stands to reason with the aspect ratios.
