Without a doubt unperking the 14 would create a monster. All the inherent difficulties of flying her aside. The 16 is simply not a monster
You can't simply put the "inherent difficulties" aside and then declare it would be a monster.
And it would not. There is nothing monstrous in the Spit 14 right now, especially when compared ot 109K, or even 47M
See the kill numbers and K/D as an indicator. Despite it's low price, it's taken into the air much rarer than any other perk ride. And it's K/D is horribly low despite this rare usage (And perk status means no hordes of n00bs "ruining it).
It's not easy to fly, and absolutely less potent than the 16 at usual MA fight altitudes.
