Why not convince him to get another 5.0 into your area?
The used you can find here are really old. A new one (N500) is more expensive than the Getaway and less ideal for what he's looking for I think.
About taking out the wings, do you think seating on the wing versus getting out on the trap would make a significant difference? I think solo sailing on the trapeze is not exactly the ideal scenario in this case.
