keep them the same and bridge the 5th&6th ports and port the sleeves to match.

it's all personal preference, some people say the 5/6th ports can only flow what the ports are already ported to but i port them anyways and have seen no noticable lack of power from doing so so i can only assume it is helping but only minimally. to notice any real gains you have to remove the sleeves however and then you sacrifice some of your lower end power for top end gains.

Don't bridge the aux ports only. There are many reasons why and it's been covered in great detail.

If you want to bridgeport, do a proper half bridge. If you are going that far, you might as well bridge the primaries as well for a full bridge.
