i love it..
i can spend a lifetime doing nothing but that...every single day.
btw, you can get *very* similar feel to the tow-in by foiling with a single skin kites working pacific rim waves(places like cabo, peru, hawaii, etc) ideally with light side shore breeze or thermal winds (...just enough to waterstart on 4-6m)
you just ride...get the energy from the wave.. .and fly the kite just enough to keep it out the water.
