Starting a new B5 Campaign - What PrCs to ban?

[seawolf69]

I have most if not all the d20 stuff, 1st and 2nd, and have never run a campaign of B5. First, I am not sure how well the 1st edition meshes with the 2nd. Also, I am not sure that all the prestige classes are not balanced.

I have heard that the Black Fist is a broken prestige class and that I should not allow it. Anyone agree?

Any other PrCs I should be aware of that will cause me problems?
