As I recall is Keldorn and Mazzy quite fun...but that was years ago...Also: Carysomyr for your 50-year old Tank..
And Minsc and Mazzy is fun because Minsc want to give compliments to Mazzy, but she whimps them off.
Korgan and Mazzy, I've heard, also have some tasty conversations.
Clearly one of these above.
And Having Hear'Dalis in your party is always fun and handy! Three magic Missile casters at once. But that just my opinion.
Anomen-->Only with Jan because Jan disses Anomen al the time
... So no
Valygar and Jahiera I don't know...
