Are you kitted with A rated stuff?
Avoid combat zone combat as the mobs there are tougher.
Have 30% beam lasers to strip shields and 70% MC’s to chew the hull.
Some shield boosters are handy but you have to use them to support your shield before it goes.
Equip a heat sink in combo with the booster to offset the heat generated.
I roll about to get the npc above me then move up, adjust speed up and down to flick the back end out (bit like a handbrake turn vertically) to get a bearing on them.
I normally run 3 pips to weapons and 3 to systems but the engines with a full boost in case I need to run away. Always have your fsd set to another solar system (high wake) so that you don’t get trapped in the gravity wells of other ships in case it goes tits up.
Set engine colour to purple for extra hope.
