That's my thought too.Why not both? Carrier is only limited to 40 ships per person, not the total number, so players can bring an explorer, a miner, a jack of all trades etc. So the correct answer is, why not both?
I'm on a shakedown cruise in a newly built Mandalay atm, and it's too good to leave behind quite frankly.
My trusty Adder carried me to Sag A and Colonia for the first time however, so she'll definitely be coming along too (some build decisions there, boost speed is so weight sensitive).
I also love my Fripper, but she'd need a complete rework to make the distances. (Thinking about that one. )
Also kind of assuming a mining ship might be needed (or at least polite). Even if there's no mining content, the expedition carriers will need Tritium I imagine.
