To start wingsurfing, a relatively longer board is ideal for getting you going. Our Slab boards being perfect all rounder.
Under 5'8 it's quite difficult to get a sup to paddle into a wave and get up onto the foil. Possible but not ideal for most. With the 6'9 providing ample volume and glide for the heavier rider.
The versatility to have a board you can wing foil and SUP foil is indeed a bonus, when it's not windy you can be out there enjoying a sup/foil and then when the wind kicks you can switch the paddle for a wing. The perfect one board quiver.
The other bonus of boards of this volume is if when winging the wind drops, you can still float back to the beach.
