That widget rocks.
Some further notes:
> Sleeper turrets (Argos, Sirius) do NOT switch aggro.
> Some sleeper BS's (Upholders?) have really crap tracking speed. You can get in under their guns and orbit at 1200m.
> Sleeper BS's can web from >50km.
> Sleepers (usually cruisers) remote-rep each other - focusing fire is often necessary.
> Target painters are necessary to light up the sleeper frigates and cruisers to max out your DPS with missiles.
> Sleepers in C3 systems attack your drones less. In C1-C2 systems, drones suffer.
> Learn the trigger ships in sleeper sites, so you can manage the aggro.
Karmadog, in my experience the sleepers tend to target in this (very rough) order: the biggest ship (eg, BS in a BC gang), ships with active gang links (Command ships), ships with RR (logis), ECM ships (Scorpions), ships with a bigger sig radius than others (Drakes with LSE's vs drakes without), ships with armour reppers. ie;
If you take a BS in with drake, the BS cops it most (naturally).
If you take a bunch of identically fit drakes, its pretty random. But if one has more LSE's/rigs than others, it cops it most.
If you take a bunch of drakes with a Nighthawk, the nighthawk cops it proportionally more. If it turns on the gang link, it cops it more.
If you take a bunch of drakes with a harby, the harby tends to cop it a fair amount.
Etc.
