1) Wyll 2) Lae'zel 3) Shadowheart 4) Astarion 5) Gale
Wyll is a braggart non-entity full of pretense and false morals. Chooses to be morally bankrupt then blames his failures/weakness on a cambion that was the only reason he succeeded? Nope! Can't even roleplay him in the party.
Lae'zel proclaims to have access to infinite knowledge via her master race yet has the IQ of and social grace of a pubic louse floating in a glass of water.
Shadowheart is that person that enters a room and turns a great party into a depressing parody of misery loves company.
Astarion is a self-serving sadistic douchbag but his saving grace is his motivations are interesting, real and understandable.
Gale is polite, intelligent and wise with a personallity to boot. Even if his condition (back story) is ridiculous at least you will recieve a helpful intellectual response instead of emotional mardarsing.
i would leave everyone of them except gale as he would probabl;y know somwone powerful enough to undertand the tadpole paradigm. The others I would probably use as test subjects.
EDIT: Also you could use Gale as a bomb to blow up Baldurs gate if you got bored.
