Eventually, if the game lasts long enough, there will be some sticks you can never kill, but they will kill you...often... I intend to be one of them. Smoke on that pipe a bit....

Wait. I don't wanna be PNG just yet.
While it is commendable to aspire to be among the best, you'll have to fly a far more diverse range of airplanes. P-51, Dora and P-47M is very narrow skill set. The best in this game over the 13 years I've been flying and training others, could win in anything. Moreover, being among the best means winning when the odds are stacked against you. This is where dueling, especially dissimilar type dueling, helps to expand skills, knowledge base and builds the necessary experience base. I suggest flying what Alex flew... F6F. Flying the Hellcat means that you won't be able to extend away from the faster fighters. They will chase you down. So, before it becomes a race, you turn into them and show them why the F6F is much better than most would think... Add some variety, it'll make you a better virtual pilot. The path to the top tier usually goes through most of the plane set....
