I also have a JP 7'0 and a NP Large foil and I have struggled a lot in the beginning, without the wedge the foil was like an anchor, too much drag to get some paddle speed to catch small waves.
I made a wedge going from 0 mm to 6 mm, how thick is yours in the front Anders ? And how did you make it?
And how much do you weigh ?
With this wedge I catch small waves a little better than with my normal sup a Starboard Hypernut 7'2x28@106liter.
I tried downwinding but couldn't get flying ...had the foil all the way in front and the stab tilted , suppose the NP large is too small for my weight.
The NP XL wing comes in September but dont hold your breath Piros said.
I contacted JP about my AOA problems and they just said they had never heard of the problem...
I thought I had got myself a working JP/NP combination but I am a bit disappointed to put it mildly...

My wedge is made of 8 layers layers of plastic from ice cream boxes. I have my foil more to the front then in this picture nowadays.
I have ordered a Jimmy Lewis Flying V 5'10 x 28,5 @105 liter and a Gofoil Maliko 280 and 200. I hope this combo will workout off the box....
