I'm currently using a Sunova Aviator Pro 6'3x24
The Elite 6'6"x22" model would also work great.
Boards weigh around 6.2kg. The lighter the better for winging. I think any of the New Gen DW shorter sups will work great for lightwind winging. If I put my foil at the front of the tracks it doesn't feel
much different to my 5 foot board, however take off is soo easy.
