Sir SprockettSakashiroI doubt that SLFs make much of a difference when ganked.
true dat! - but so far the only "ganking " I have had in open while trucking is NPC pirates. I am operating from Alioth System (permit required) which reduces the gankers (they are more about ganking than game progression) - so an SLF could be of use to me - also if being ganked then I can use it to screw with the instance.
If NPCs are your main concern, you can do without MRPs/HRPs. Just make it a shield tank and install turrets.
And if you do happen to meet a ganker, try combat logging.
