If you want a powerful and spell-heavy HoF party, I'd drop one or both of the F/Barb mixes, even though there's really nothing wrong with the characters at all. A dwarven Battleguard of Tempus is almost as good physically and has the spell options to go along with it. You could also add in a druid, for spells, summons, and (with the mod) shapeshifting.

I've taken two sorcs before, and liked it. However, why make them both the same? I'd take a human (for quicker spell access) and either an aasimar or a drow. I'd tweak the stats, too.

I'd really recommend taking a couple of rogue levels with your wizard.

Hmmm, about the same advice as kmonster.

Another class combo I really like is a drow bard/wizard. You can level-squat it for a long time and still have it contribute (via the Luck song), and it can be a great caster in HoF.
