I'm going to jump right in here and say this is a very bad idea, and stands to cost you a lot of ISK for no real gains.
Firstly, you never take a capital - let alone a supercap - into a belt. That's begging to lose it, and it's substantial overkill.
Secondly, you can't physically take a capital or supercap into most complexes, as deadspace gates won't allow caps.
Thirdly, any anom or plex which does allow entry will be a walk in the park for a PVP fit carrier - so a supercap would be a vast overcommitment in terms of risk/reward.
Finally, a supercarrier is a huge undertaking - you're basically commiting one of your characters to spending the rest of their EVE career floating in space.
- You will need to run and fuel a
powerful POS for it to live in, and
it WILL be scouted and attacked.
- You will need to provide it with fuel
to move from system to system.
- You will need 3 or more other
accounts to provide capital support, logistics
and cynos for the supercap (it can't
dock to repair, replace
So, in other words... don't do it. Supercaps are only viable as PVP ships for wealthy players with the support of a healthy PVP alliance. If you insist on heading to 0.0 for this reason, stick with a carrier.
