Best plane vs B17G

[iamcow]

I was playing against a B17G in a dogfight today in a K-4. I won convincingly (12 kills to 1 death from the bomber), but it took ages for the b17 to go down, even vs good long bursts from my 3 cannons and 2 mgs.

So I was wondering if you folks reckon there's better planes/tactics/guns to bring down 17s. My tactic was to come from straight above or 12oclock high where his gunners can't cover. (Apart from rockets of course.)
