Just a note, you may want to add the Mjolnir SHF has a ship choice. (It is, afterall, an RFP ship)
I've been using a Police Guard tagged and ID'd Mjolnir for a few days now as an indy cop and I have to say it makes a fantastic customs & interdiction ship for the following reasons:
1. Its armed to the teeth, 4 gun points and 4 turrets.
2. Is as agile as most standard bombers
3. Built like a tank with a shield to match.
4. Can mount an SN or Nova launcher AND a CD, which makes it great for stop and searches, and can actually destroy uncooperative traders or smugglers on its own without having to shout for the RM.
5. Its not actually that big, and its looks are starting to grow on me.
Hey, I might even be interested in joining if I can keep it ;)
