I'm 88 kg and have a 95 ExciteRide that is pretty old. I've been dicking around in small waves on it. Its better than nothing and my custom wave boards from the 80's. I bought a 6.5 NCX to do the LOC but just couldn't get on the plane and pulled out at half way. I reckon it was 15-16 knots at the start. A week or so ago I tried a 104 MagicRide and definitely would have been able to get on the plane with it. Gybes nicely and much lighter than the ExciteRide. I'm going to buy the MagicRide but probably should get a dedicated wave board again, not the least for the short fins.
