"Because you can" is the reason I bought my second Cutter, tbh.
I lusted after this ship in CG after CG as they left my Type-9 in the dust every time, so for a good year I was smitten with the Cutter once I had it. But, now having the biggest hauler in the game, my love of hauling began to wither and I started focusing more on combat. After blowing several billion into making a formidable war boat (second cutter, BTW), I grew frustrated with it. While it had great shields, it wasn't putting down nearly enough damage. So, I mothballed the warbird while I bought and engineered my FedVette "Lingenfelter."
That retired warbird has now been repurposed to yep, you guessed it, a miner named "Minter." The other one, "Irregular Catering" remains my deluxe hauler for when I get the hauling urge now and then. Still a fantastic ship for some things, and almost as fun to fly as the Type-9.
