If Dean is out there(resident rave expert) he may comment on his feelings between the two, but if I had to choose I'd pick the tri-foiler. The rave's flight attitude is controlled by a joy stick that operates a flap on the back of the rudders T-foil and one small goof and it will nose in like a picthpole. On the tri-foiler the flight attitude is controlled by the sensor feet which moves the L shaped foils fore and aft. All automatic. The rudder has a T- foil and that's it. Less to do lets you concentrate on trim and steering. Plus it's a Hobie so you will be able to get parts easy........( in case you run aground)

My .02 cents
