Caveats:

I am NOT a powergamer, and therefore am interested solely as it affects play in SoA, not ToB. Tactically I prefer to play an artillery+finesse game, and therefore stay light on tanks. Please keep this context in mind when making replies.

Currently:

Protagonist: "Fish," Ftr., Reformed Assassin and Pickpocket, TN. Primary proficiencies in longsword, 2h-sword, and crossbow, w/ occasional outliers for amusement value. (Modeled loosely on "Old Man Fish," from Glen Cook's "The Silver Spike.")
Viconia
Edwin
Jan
Yoshimo
That Dwarf

I intend to restore Imoen into the party, as she amuses me.
Therefore, when I get rid of That Dwarf, as I surely shall (personal bias, he simply irritates me), I have a choice before me... amuse myself with Nalia, or with Cernd? In this party, which of the two provides the greatest amusement value?

Or, entertaining a tactical question, if one were picking up all the wacky ones and opted for Cernd, under what circumstances would Nalia or Haer'Daelis be sufficiently interesting to justify replacing Edwin, who is long on spell-slots and short on divination and shortbows?

Yes, I know I'm mage-heavy... very much so. I just enjoy all the finesse options that such a party provides... and the lovely chaos that ensues when something gets screwed up and chaos ensues, with the protagonist bleeding profusely and Edwin parrying desperately with a stick, while Jan gnaws on somebody's ankle...
