I bypassed the Clipper with my main account, but I now have two "glamorous assistants" (alt accounts), one based in the Bubble and one in Colonia, and decided to equip each one with a Clipper and a Courier.
Each has a prismatic shield in the size 4 slot, so I keep the two biggest slots free for whatever I'm doing. Default configuration for mission-running is a size 7 cargo rack and a size 6 Business class passenger cabin. When I relocated one account to Colonia, I used a 7B fuel scoop and a size 6 fuel tank. That was handy for the neutron highway, because I could make a lot of neutron jumps on 80t of fuel and then refill very quickly.
I also have a spare size 6 cargo rack and another passenger cabin, and for combat I have a size 7 bi-weave shield and a couple of Guardian shield reinforcements.
So it's a handy multirole if you're prepared to keep swapping modules.
