Hi Nick, interesting as when I asked our design team if you can use the 1250 with a SUP/Wing, they thought due to it´s design for higher speed windsurfing, that it would not work for the SUP´s...but wing foiling is of course faster than normal SUP or Surf foiling, os maybe it works ok? I´ll give that a try next time. The biggest problem is the fuselage length/position of the front wing, of windsurfing vs SUP.
For Kiting I think you may find the front wing a bit too thick, as generally you need way less lift for kite foiling, but let us know how it works out. for normal SUP or Surf foiling, you will probably need to go for the Aero foils, as these are slower and match the speed of the wave better/create the extra lift needed to get up and go/don´t run away from the wave.
