If the wind is very light and the waves are good then it is more suitable for strapless. Someone needs to invent a kite that can go straight upwind to let the rider cut back upwind into the pocket.
When its windy and cross onshore, then it suits straps more. I don't think it would work to incorporate jumps like the King of the Air unless the waves are totally closing out. They could pick out freestyle moves that are going to flow with the waveride and start to incorporate them into riding the wave instead of just a plain aerial.
I can't think of any kite vids that I've seen to illustrate that, but this is windsurf waveriding with freestyle tricks incorporated into the aerials, but they still flow and fit in with what the wave is doing.
