I have ridden the board a couple of times and am very impressed.
The board feels like a 68, not a 75. This is mainly due to the fact that there is very little length in front of the mast track however most of the volume is there due to its width. The back half of the board is why it feels like a small board, that's the secret of it. The board also has very nice deck pads and foot straps and looks fantastic.
Going upwind the board can point fairly high without sliding out or coming off the plane.
On the wave it feels like you are riding a surfboard not a windsurfer. On bottom turns the board grips very well even in choppy onshore conditions. The top turn is loose and slashy but still with enough grip so the board doesn't leave you.
