Thats a simple solution, after killing the first group tell your wingmen to attack mission critical targets using d-pad down then d-pad right; then whatever targets they dont attack you go for. Let them work by themselves, just focus on downing your targets as fast as possible.
First time I tried that tactic it worked and complete the mission!

I don't have the Spitfire XVI yet, and I don'teally plan on using it, but how does it handle now?

The wings were clipped solely to enable a better roll rate at low altitudes. This was first done on Mk.V's after the quick rolling Fw-190 appeared in late 1941, but it was eventually done to many Spitfires.

By all means, the higher wing loading of the Spitfire XVI (with only 231 sq ft. of wing area and a similar weight and thrust to the Mk.IX which has 242 sq ft. of wing area) should make it more unstable, faster rolling, but wider turning than the Spitfire IX. Is this evident in the game?
