The few times I flew a fighter, I tend to use the 2 a bit until the 3 came along. I just love how the 3 handles, and having more ammunition for the 20's makes it easier to stick around longer. I know the 5 has better guns and and more power, but of the 3, the 3 is my fav. I seem to "click" with her better.
I'm cray-cray, and would up with 100% every time regardless of being off a CV or off an airfield. Convergence usually set to 300, but at times I would bring it in to as close as 200.
