I'm just guessing here, but somehow we have to choose a plane to fly in right? How is this supposed to be done? In previous duels, plane choice went to the team listed first for the first flight, then alternating after that. May I suggest an alternate rule?
First plane is chosen in the following manner. First listed pair chooses 3 different planes of different types (Spit I, Spit V, Spit VIII would not count) and the other team selects one of the three planes to fly, then the first match is flown, and the looser of the flight chooses the next plane. This would not be like the first flight, they just choose the plane they want and the next flight is flown in that plane.
If this has already been determined, please ignore the above.
