Aside from the Spit V, I believe the Spit IX was the second most produced variant of the Spitfire (Dont have my Books off hand)
I dont touch Spitfires. I hate them. And I hate fighting the Hordes of Spitfires in the MA. But on the other hand, I dont see any good reason on perking the Spitfire Mk IX. I hate the fact that I see them al the time, but hey, thiers no point of complaining. Kill em!
I dont like the idea of perking an a/c just because its used the most in the MA. What would happen if the Spit IX was perked at 8 points, just like the CHOG? do you actually think the Spit IX numbers would go down? I dont think so.
