Haha, now that you mention it...I've kept some cargo space. Spent some time in a RES, and doing some kill pirate missions yesterday, and when I was finished I took a load of gold for some extra cash. On the way home I was interdicted by a deadly Anaconda. Great I thought, some extra bounty! But I was wrong. That thing had at least one beam turret and my shield was going down so quickly I couldn't believe it. Used two or three shield cells and still lost the shield. And it seemed like almost immediately after that: "cargo hatch malfunction"...there was my gold spilling out! I then decided to break off and jump back to SC, but he followed me and interdicted me again. This time I just waited for FSD cooldown and went back to SC right away. Reached the station, and what do you know...he was after me again (without interdiction, and I hadn't seen him on the radar either on approach...that was strange). Unfortunately he didn't follow me into the no fire zone, but turned away and jumped out.
After the battle, I remembered that I didn't use my chaff. That might have helped quite a bit. And I found that my loadout (4 medium multicannons, 1 large beam laser) didn't work too well against that ship, as I couldn't take out the shield quickly enough. I think I'll switch to a more laser heavy setup.
Otherwise I liked the multicannons while fighting in the RES, they're quite effective once a target's shield is down. But it was a LOW RES, and so had few higher rank opponents.
Overall, I'm not too sure yet if I like the FDS. It really turns very slowly, and drifts extremely. I don't have A grade thrusters yet, maybe those will help.
