Capships can hit non-strafing ships rather easily. If you take away it's ability to strafe, then you have a ship that can't do its designated task. I think that bombers need to be about the same kind of target to hit (through size/manueverability adjustments) as the Falcata through to the Praetorian.
LF's need better turn rate and strafe speed than their VHF counterparts, if they're light, then make them light. The Loki, although big, has the turn speed and strafe roughly how an LF should be. Of course there can be adjustments either side of that, and not all ships should be the same, however I think that the loki is about right for a middle of the line LF, the lib being at the top, and turn speed like the Scimmy is a tad too slow (not by a lot though).
VHF's are the compromise ship. I love my VHF's and you're right, they work (kinda) now.
