While fighting a bomber in a VHF, the trick is -never- to joust... Slide at a different angle to the direction the bomber is headed, and he/she will find you rather tough to hit with a supernova...
NEVER box against a bomber... it's asking for a torp.
Anchor turns are your friend in any fighter class combat...
You can end up somewhere totally unexpected for your opponent with clever use of the reverse key.
My Xeno taiidan has four black widows, supernova and a train CD... My worst nightmare is light fighters, who are always so close to you that you never really have time to line up a supernova. Maybe if you're struggling against bombers, try getting an LF to cope.
