My plan:
Mining: bring the carrier to my mining system, with my Type 9 Miner doing the mining upon arrival. It returns to the carrier, I switch ships to a Cutter which can carry all the cargo and is much better suited to dash to the best station to sell the mined goods at. This will save me time in jumping and increase security.
Trading: move my carrier to a system with a great bulk trade route active. Hop off in my Cutter and trade. When the server tick hits, and that route moves 300LY away, just move the carrier there. Saves me a bit of time jumping. Also allows me to store my Corvette and Vulture for pew pew when trading bores me.
Not sure what use it will be for bounty hunting. For CV battles, again, it'll be faster to move the carrier than moving my Vette. Once the day is won, I can move the carrier back to where ever I wish to go next.
In effect, I'll spend less time travelling, and more time doing stuff, if things work out as I imagine. That's a pretty good improvement, imho. However, if the buy in cost or maintenance / fueling costs are too unbalanced on the high side, it may not make these plusses worth it. So....I hope I can use it this way, but it's TBD.
