Well, I guess we'll have to agree to disagree. I dont personally think that a simple +1 in dogfight and 2 inches in move sets the Starfury apart at all, given the relative gains (hull, firepower) that the Thunderbolt has.
Combined dogfight value for 3 Thunderbolts: +3. For 3 starfuries: +4.
the worst opponent you could come up against is a Tishat or ISA Nial - and even then you can hold them in combat for 3 turns and take 3 chances for them to roll low.
Also, you can move 20 inches to get the hell away from dogfights, in the event that you lose initiative. Even if the enemy does get onto some of your fighters before they can fire at their intended target, chances are it'll only be 1/3 of them.
Singly tbolts simply aren't bad dogfighters (+0 is bad, IMO - and there are plenty of fighters with that which come in similar numbers for the points and dont have the 2+ dodge, hull 5, 4 inch range to boot).
