OK, my new toy has arrived!
A bit apprehensive. I am 56, 100kg, and never foiled on any support, nor flied. A am competent in SUPing and Windsurfing though, and some surfing abilities... I will share my experience here

First the gear: A Gong SUP foil, big wing (the large version), full carbon, 2' / 60cm mast, and a "Curve" board 8'9"x31" x 135l full carbon sandwich deck, Tuttle Box & straps added by the Gong team: with the pad it means 2kg more than the production board at 8.9kg.
Gong put the rider in the center of the board,with an advanced position of the foil & straps. This this more natural to paddle with the feet in the straps, and to balance while flying. The angle of the foil is designed so that the foil is flat while paddling, so the foil doesn't drag while paddling, a nice touch.
