Oh my god, I can't resist posting.
The Spit 14 has always been at the bottom of the list for kills/perk every tour. It has little family resemblance to its little brother, the XVI, lacking its roll rate, its turn rate and radius, and its easy handling qualities.
But this is what you'll get when what is perked is left to subjective judgment, and not based on some kind of objective study of aircraft performance and characteristics. Even a flawed attempt at the latter would be more rational than what is in place today.
