I have a Cobra. The hardpoint spacing is pretty far apart. I now primarily use mine for bounty hunting; I really want to sell it up for a Viper though, but I'm having a real hard time letting it go.. The jump distance and cargo space is excellent compared to that of the Viper! Plus, all of the extra internal compartments..

Boo!
Unfortunately, as great as the Cobra is, I feel that I can
only use gimballed weapons. It's not ideal, especially considering the vast reduction in damage compared to fixed weapons. But when coming up against smaller targets [Eagles, Sideys, Vipers] you can only really hit the smaller ships with one set of weapons [port/stbd]. So, as a result, I use gimballed weapons. It gives me the ability to unleash all 4 hardpoints upon my targets. Since 4 gimballed weapons > 2 fixed weapons, at any one time.
I've found that the best gimballed weapons are the MCs and Beam Laser. I don't think I can afford [or haven't found] high powered gimballed pulse/burst Lasers. I've found turreted pulse lasers, but their damage is woeful compared to that of my gimballed beam laser.
The beam laser isn't ideal, it 'waves around' far too much before getting a decent lock... Maybe that will change when I get my joystick!
NB.
The beam laser does
excellent damage against sub-targets, EG. If you're up against a larger/tougher ship; Asp, Clipper, etc. and you target their FSD or Power Plant, you can nail that equipment in no time with it - Whilst the multi-cannons also hit it, they obviously don't always hit their mark and deal massive damage to the hull as well!
