What does everyone think is the best party you can possible get in Baldurs Gate 2 without cheating.

Reply ASAP plz

Korgan
Keldorn
Jahiera
Viconia
Edwin
Jan

Substitute own character where applicable
(ie. Mage for Edwin, Barbarian for Korgan etc)

The evil characters are slightly stronger. If you play a good character, the best party would probably be:
Minsc,
Keldorn,
Jaheria,
Aerie,
Imoen/Jan Jansen

I try to have two mages and two healers in the party.

Be'eth a Mage
or a fighter/mage
one can never have enough magic in a party

let see
Edwin- supermage
Viconia- very good cleric
jan- good thief and reasonable mage
Keldorn- saves you true sight places BUT you have to give him gloves of dexterety
Valygar- one can't find any better katana wielder

Provided your character is a fighter who can tank:

Korgan
Jaheira
Jan
Viconia
Edwin
