The Mega seems a bit better with the Warp Stabs off. I've also diversified ammo (anti-mater being a mite expensive), and worked out ranges. My long-range ammo hits at 40k, my drones can go in at 35k, and my shorter-range ammo kicks in around the 25k mark.
Frigates boil under drones; cruisers seem to wilt under shells, and Mal left me room for a tractor and salvager so I can even hoover my own wrecks most of the time.
Did Human Cattle 5of5; thought about the fleet, but then noticed there are no bounties (because they're Amarr) so I'd have to be sure I could get them all before I'd get the salvage. Decided to leave it alone. Still got almost a mill between fee and bonus. Rounded off the take with a L1 mission: 2 frigates. Didn't even need to fire: drones did both of them. Good fee -- must not have been taken for a while.
