I used to replay both games around Christmas time, my usual party is:
BG1: Imoen, Minsc, Khalid, Jaheira, Dynaheir me playing a tank (paladin or warrior)
BG2: Imoen (or Nalia), Minsc, Jaheira, Aerie, Mazzy still playing a tank
a couple memorable playthroughs were with:
BG1: Imoen, Ajantis, Edwin, Garrick, Xan
and
BG1: Imoen, Tiax, Yeslick, Montaron, Kagain, Shar-Teel
BG2: Imoen, Keldorn, Jan Jansen, Nalia, Anomen
and
BG2: Imoen, Haer'Dalis, Aerie, Cernd, Minsc (+Yoshimo)
