why perk it in the first place? Just learn how to fight it like all of us learned to fight the lalas and spits. if it's a problem with it out running you, fly a lala, outtruning you? fly a hurri or a6m. For the love of god, the perk system is fine LA7's, N1K's, Spit16's all have an eny value of 5 which is good enough IMHO just fly smarter.
oh yeah, I vote NO
