once i found 3 lakons with 3 eagles each as escort, i accidently scanned the wrong ship = the eagle, and guess what the pilot did? he escaped

so my tactic was/is:
scan each eagle, let it evade, follow and kill it. rinse and repeat, until a lakon doesnt have anymore escorts, then target the cargo-hatch to let it lose some canisters, then target the power-plant to explode it, dropping some more cans.
when you decide to scoop up the goods, make sure you do it as quick as possible, since the canisters have a limited lifetime.
concerning the bounty: its not worth the risk if it (a lakon) only got liquors or other "worthless" cargo. at personal weapons or gold, it justifies the risk/effort. dont forget that sometimes after you attack a lakon (w/o escort) some reinforcements will appear, thats what made me poop my pants the first time when i thought "oh nice, a lakon without any protectors, ima kill it for breakfast". i was dead wrong - literally. arrrrrrgh
