Tim,
the F3 was never built to dogfight, simply to stand off and blat fireworks off at any passing a/c with red stars on them!!
Today's F3, and I hate to admit it, is actually bloody good bit of kit. It has ASRAAM, AMRAAM & JTIDS. These attributes, along with it's speed allow it to get into a position to fire well before most other a/c and that my friend is how to win BVR engagements.
Much more fun flying a Tonka where it's supposed to be mind... low & fast!!
Despite my short campaign for the Tonka though, my vote has to go to the PR9. She retires shortly, with nothing out there that can replace her pound for pound.
