While i have a collection of ships, the clipper still sees use for two things:
1. Laser mining. It has enough slots to carry everything i need and big enough slots to carry home the load of a normal gaming session here. (Would i do 4 hours mining sessions, I would pick a bigger ship, but for my usual time slots, the Clipper works well. ) And due to it being faster than alternatives, flying from one rock to another feels a bit better.
2. Freeing slaves from the Kumo Crew. Again, thanks to its high number of internal slots, it can bring everything it needs to interdict a freighter, launch hatch breakers and collector limpets, and still have sufficient cargo space. While also being fast enough so nothing can outrun it, massive enough to masslock many targets and armed well enough to hold itself in a fight. Yes, i wants gimballed weapons, but with those mounted it does quite a good job.
Of course, while i use this configuration only once a while when i need merit to get some PP equipment, anybody operating on the wrong side of the law might find the same properties of the ship quite appealing when acquiring cargo without paying for it...
