Fighter/thief vs fighter->thief

I've never played one and I think it would be interesting. Not sure if I want dual or multi though because fighter hla seem pretty vital but the dual gets grand mastery and can be a kensai/berserker.

I guess I can always EE keeper in a kit on the multi and then that might be better. If I do that would I rather do berserker, kensai, dwarven defender or assassin?

I don't think grandmastery alone is worth losing fighter hlas...

I'd probably go with staff, 2 hand swords and halberds since I never played a 2h fighter...
