Overdrives are ok, they give more speed and don't affect your hull, but they reduce your cargo hold and, whilst they make you go faster, they don't increase your aligning speed when you need to warp out fast. It's a choice really, Overdrives will move you faster, Fibers will turn you faster
Might even be worth looking at Ballistic Control Units if you can fit them, they'll just up your killing power a bit, but when you're doing a mission, and things get out of hand, it's handy being able to get out fast
Oh, and Grug, 2 miner 1's and a Cargo expander
