I come from a windsurfing/windfoiling background and have been winging exclusively for the last 2 years. I like to be well powered (better for jumping) so I'm in the harness most of the time except when flagged on a wave, gybing, tacking, jumping etc. For me, my harness is nearly as loaded as it was when I was windsurfing (not quite as you need less power using a foil). If you look at the above picture, the wing is orientated in a very similar way to a windsurfing sail when powered, so I'm getting more or less the same sensation to windsurfing. It's just more versatile in what you can do (huge wind range, super tight upwind angles, swell riding etc). As Guy Cribb says, it's the new windsurfing.
