Equal pilots it is close, we should DA them and switch Junky, I think you'll find it's a tough fight in a Brew vs a Ki, tougher than many think, the only thing it has is guns and the ability to absorb more damage. Like I said, I've fought a ton of Brews in the KI, I'll punch up the stats thing program again, but I know I haven't lost to one yet, but have no way of telling the quality of all the pilots, plus it's the MA, where of course there are piles of factors, SA being one of them that doesn't really matter in a straight duel.
Once the turn fight is on, in any dimension, vert or horizontal, it isn't long before the Ki comes around behind the brew, and then it's over so long as the Ki keeps it out front long enough to put enough of the weak twin 50s into it.
It's lethal IMO, for many reasons, I'm no super pilot, but have had a couple tours of over 10 kills/hour and 4+k/d in it all never climbing over 10k once. Guys like you or Bruv or any number of other KOTH type pilots would demolish in it, even more than the Brew, as it's far more elusive and your death numbers would be far less than in the Brew, while kills would only go down by one or 2 per sortie IMO due to the guns.
