Sunder Questions?

[Drakeskull]

When Making a sunder attempt as an attack do you use your current attack roll that you make it with or a attack using your full bonus? Also if you drop someone and make a cleave attempt can that cleave be a sunder attempt?
These questions involves some epic charicters fighting a bunch of frost giants at one time. That you in advance for any light you may be able to shed on the situation.

Yes, if you try to sunder something on your third iterative attack you do it at 10 less BAB.

And as long as the cleave targets another character I cannot see why it should not be allowed to be a sunder.
