I gotta admit - I just dont run into them that much. But, I tend not to join the base hordes, and the La-7 makes the most sense as a point defense plane -- so maybe that's the reason.
Anyway, I find that when I do find them, jsut have to use my plane right and there isnt much problem. Break, let em come back, break -- and pounce on the low E dweebs trying to turnfight in a dragster!!
I guess I'm more vulnerable to the slow and turning Nik scourge with my flight style....
