If I wanted to go through the game with characters that bickered ALL the time, who would be best. Jan Jansen would be my first choice, then minsc, as those two go at it hammer and tongs. But who else would bicker with them?

How about:

Keldorn
Viconia
Minsc
Edwin
Aerie
PC Thief

I know that Anomen and Jan have a couple of fun interactions, as well as Mazzy, but I don't know who else.

I thought Keldorn and Viconia would kill each other, plus she was a bit dull. I heard Korgan and mazzy interacted well? I should clarify, Bickering as in jan stealing boo all the time rather than one member nearly killing another.

Imoen and Korgan have a good interaction.

Jan has some fun bickering with Minsc and some hilarious bickering with Anomen; so these three are good to have for bickering.

Minsc and Edwin also do a bit of bickering. And I think that Edwin and Valygar have an interesting spat or two...but I'm not sure about this one.

So I guess this party would look a little like:

PC
Minsc
Jan
Anomen
Edwin
Valygar

Or you could also opt for having two of the romanceable female NPC's in your party...I'm not sure, but I imagine this might cause a few good arguments ;) .

Mazzy/Korgan is down right hilarious.
