I agree Karnak, as much as I love the little F4, IMO a smarter Spit16 pilot will use everything other than turn rate/radius and can win a majority of engagements.
What really interests me is the Spit5 vs F4 match up. It's very close, and sort of the opposite of the Spit16/F4 setup - the F4 has superior power and climb, and so long as the F4 doesn't get sucked into a low speed turn fight, and makes the Spit5 fight nose up, IMO it's the F4 that holds a better hand of cards. It's my favorite fight to run into when I fly the Spit5, always fun times.
