Colin,
That's interesting. I struggled with visibility in my old two seater, not so much straight ahead but the problem arose with the hood up and my eye line was above the solid part of the side screens. Things are better with the easy up hood on the newer car but I had not realised that this was different in height to the old four seater screen. I guess my solution would be an older two seat car with a four seater screen which was an option I believe.
Bob.
