When some time ago the Viper claimed a 1.04 rating "because of weight" I was already thinking Greg was playing on 2 horses.
Now the worst thing that could happen is that Greg sells his Viper as an F104 in France, because then Nacra, Hobie and AHPC have a F104 and it will be difficult to encourage Cirrus or Mattia or anyone to built an F16 compliant model.
Again resulting in difficult sales in France and difficult class building.
