I just tried to put my post in but it got wiped when sending! So here is my summary for my new 4 metre wing. I haven't tried it out yet.
Likes: Handles are closer together & should be easier to reach compared to my 6 Metre Cabrinha X2 Wing.
Yes the handle nuts sit in a recess.
Pump valve is simple to pump hose connection. No need for an adapter.
Build & quality looks great.
Bag does the job with backpack straps instead of one shoulder strap.
Has repair patches & washer.
Concerns: 2 hoses from Leading Edge to Strut. Would another valve be better?
Hand leash length. Is it long enough?
The bag zip got caught in the mesh. Took about 10 minutes to free it without breaking the zip & mesh. I managed to free it by holding the mesh down from inside the bag to pull the zipper up.
Hopes: To get up on foil easier than the Original Naish Wingsurfer.
Less back winding & upwind ability than my 6 metre Cabrinha X2.
