The planes I engage the most in combat are P38s (because I know I can kill em quite easily) and Spits (because I phear to get em on my arse).
When a plane is on my six I definatly phear the Spits. But I dont phear them so much that I dont engage them agressivly.
A plane I tend to be much more conservative against is the N1K. I know that when I engage it the slightest butterup will result in me going down.
The most annoying is BnZing 109s and 190s. Its not that I phear them so much as one having to pay so much attention to something one cant really do much about.
LA7s I dont phear that much mostly because I know that I can always out turn them.
What I do phear though is combos. N1K+LA7, N1K+190, Spit+LA7, P38+190, ect ect. Combos where there is a good turner and a good BnZer.
I really have a hard time fighting this in my Yak because I can either outclimb, out run, out turn one of them but not the other. Outmanouvering one will get me killed by the other.
