A well balanced freeride windfoiling setup for me is basically all front hand/foot with the back hand/foot along for the ride.
Can't agree more, for me the only reason to use the harness is to get back up wind, helps with keeping mast foot pressure when you absolutely need it to power back upwind. Caveat : only use small sails chasing swell.
Some track porn for good measure
