Effdub,
The problem with the RPS is that you end up with Bf109E-4 vs. Bf109E-4, then Fw190A-5 vs. Fw190A-5 and then finally Spitfire MkXIV vs. Spitfire MkXIV. Unless you set it in a HA, and that introduces a whole new set of problems, such as most people flying for the side with the better aircraft.
