Effiecient lvl 4 running ship advice

Large micro jump drvie Dominix sniper fit can do any L4 mission. Any. With only two tanking mods - rest is damage and application. Instant application, without lost volleys due to missile fly time. Trick is the unique drone range bonus, which allows you to get over 100 km optimal for 3 kind of T2 sentry drones and even Garde has 100 km falloff. So you LMJD away, blap what you need (range is your tank) and LMJD back, kill the rest.
Rattle snake will give you more paper DPS and should be your next step if you want full room clean up. You will be partly limited to two damage type for your missiles and your drones will have meh range. Still will perform slightly better, than Dominix.
Many L4 missioner do just few blitzable missions and use Machariel for that. Google mission blitz guide for fits.
CCP once upon a time made a tool for the job. It is called maraduer class ship.
