I think a shallow drop ergo bar (such as the 3T Ergosum posted earlier) look amazing and would be super comfortable. My problem with the ergo drops on my road bike is that since I prefer to have my bars angled slightly upward for riding on the hoods, the angled contact point on the bottom becomes angled too far up. I sort of tweaked it around to be a good compromise, but I'd prefer to just have Ergosums and be done with it. Besides, I don't ever need to dip that far down most of the time anyways.
