The only thing a Type 6 is good for is stripping down, removing its shields and weapons and hauling 112T of cargo. That's why it is cheap. Always submit to interdiction to reduce cool down time for FSD and boost, boost, boost away. Four pips in ENG and two in SYS permantely.
Fighting in one is suicide.
Not quite true. My Type 6 only does 96T of cargo, as I do keep shields, even a KWS and Discovery Scanner. Now, I wouldn't be crazy enough to fight other players in it, but for NPCs in anything up to and including Cobras, I haven't gotten in real trouble yet. Not that I am looking for fights, but half the time if the interdiction is strong in my opponent, I just submit rather than be forced out of SC.
This leaves me two options.
1: If NPC in Asp or larger, or player no matter what his vessel is, full pips on engines and auf wiedersehen!
2: If NPC in Cobra or smaller, full pips on shields and deploy my two heat-seeker pods and kill the not so smart AI.
Sometimes, I've taken out NPCs in Eagles with one volley, though most assailants require 3-6 volleys. I've only spent all my rockets (12 volleys) a handful of times, and only one of those was it not enough to get the kill outright. Now it is expensive with them rockets, but I think I'm a little bit on the plus side nonetheless. I also travel with Point-Defense should missiles come my way, and Chaff to throw off the aim of those gimbal and turret weapons.
