Oslecamo's Monster Classes

[Amphetryon]

I've been asked to DM a game where everyone plays one of the Improved Monster Classes that Oslecamo has compiled, primarily on minmax. Having not DMed for an all monster campaign before, are there any particular options I should watch out for, on either end of the power spectrum? They'll be running on a 26 point buy, if it matters.

I haven't played with them myself, but I do remember a conversation where it was implied that the attempts were not meant to be balanced against normal characters.

I have read though the classes and played with a few of them.
They are generally fairly balanced internally when compared to an optimized wizard, but i recall there being a few of them that seriously beats the power curve over the head.

And so the best advice i can give is to firstly read carefully though every class before allowing it in game. And secondly accept that the group is going to be extremely powerful, and have some obscene dc's on some of their powers.
