I'd be happy with just a few more EIs or even some EIIs for Alvin. Those long flights from St. Pol get tedious when the only enemy planes you see are too dangerous to go after.
At least Ambrose is having fun in his Bristol Scout. Nothing to worry about for him except fire, collision, and forced landings gone wrong. It's unfortunate that I never see any Pfalz Morane copies anymore. I'd like to try the Scout against one.
