Hi Peter
4 years of kite foiling just jumped on the wing, winging 90% of the time now
kitefoil is just for sub 15 knots now
in term of wave riding much better experience ! I was addicted to supfoiling before
my prefered front wing is the gong xl pro, 2,4 l , 1900-1700 cm2, 92 cm span
tried my big wave alpine wing 1200cm2 without much success, so no hope to use the same wings,
a 1200 with more volume and high aspect ratio might work but it will be boring with a kite.
I am reducing the board sizes,started at 6.3 130l, then 5.8 110l which are supfoil boards
and now going to 5 feet, 90l (not supable for me anymore)
I believe that the sails and foil will progress quickly , so the speed should be comparable to a big wave kitefoil , but it is not the main point, winging a small shop of 2 feets is already a wave to surf, a lot of fun!
when you have 4 feets you are in big wave riding
I think it is impossible to reuse kitefoil equipment , but you can use the same board and foil for supfoiling and winging with 2 mast sizes.
