The only weapon you could use that might beat that would be an Ethereal Death Cleaver, but with the Barb's Critical Strike, it can be debated. One of the j00bs would be willing to devote the time to explain it, as I really don't happen to be interested in this game enough to research it.

I would say stick with your EBOTD for now. Charms, you'll likely want a good stack of 3/20/20's.
