Grats on gettign to the Orca Alptraum!
I've been using mine as a mining base, I'm in 0.5 so not as much to worry about getting ganked but do have the skills for a decent tank on it.
My routine is to fly around looking for an exploration site with asteroids I can mine. Then I have my Orca pilot warp to the exploration site (or a belt if I didn't find a site), I have two miners who follow in frigates with salvage kit, they jump into the two hulks I have in the Orca's ship maintenance bay and start mining the roids, emptying their cargoholds into the Orca (or using cans if not close). Meanwhile I have a hauler who runs backwards and forwards emptying the Orca's hold. Once I'm done mining the Hulk pilots swap back to their frigates and salvage all the rat wrecks.
That's 4 accounts and that keeps me fairly busy (no breaks longer than a couple of minutes), when I reopen a fifth account I'll have an extra Hulk miner and I figure I'll strip a belt in under an hour and I'll be busy playing all that time. Gravimetric exploration sites are best as you get some really big asteroids that take forever to mine out, plus better rats.
Adding in salvaging makes a difference to your income, you'd be poppoing the rats anyway so why not make something from them?
I wish they made something like the Orca for multiboxing mission runners...
