Currently the best PvP combat clipper build I created and have used for a while is this:

Cargo hatch, FSDI, fuel scoop on low priority but FSD is left at high priority for fast frame shifting after closing hardpoints. One 4 and one 2 SCB are used together, the 6 SCB is used by itself.
With prismatic shields the new best build will be this:

The prismatic shield can't be shown so the differences are from what is shown:
+ 80 mass for a total of 950 tons with full fuel
+ 2.45 power used for a total of 31.88 deployed power usage
+ 86 Mj shield for a total of 514.04 Mj shield (with 2 A class boosters as shown)
The differences from the original build are this:
* + 15 tons of mass. Good.
* Besides the same priority settings, FSD must now be set to low. Quite bad, can't find an acceptable way to fit this unfortunately.
* Sensors downgraded from B to C. Meaningless, you used B class to increase mass, not for the increased sensor range and the mass loss is made up and then some in the shield.
* Shields lose 5 Mj of power. Meaningless.
AND the reason you go through all these changes...
* Able to fit in double chaff for PvP or an E class scanner or two in their place for PvE with basically the same amount of shield as the original build (which used FOUR A shield boosters instead of TWO).
Total mass determines who comes out ahead in rams. Speed of collision determines total ram damage distributed. That is why you want a high mass clipper for PvP. The prismatic shield makes you a bit heavier with the added defenses of double chaff and you keep almost the same amount of shield, the only real negative being no longer able to quick FSD after closing hard points.
