In that case, my opinion is:
Dr. O if you need heavy bone work.
Dr. Z if you don't need much bone work.
Dr. DiMaggio and Dr. Spiegel are also good options, both similar to Dr. O, but each with their own drawbacks:
Dr. DiMaggio's being location - if you have a complication, this can be a bad thing.
Dr. Spiegel's being hit-or-miss results - from what I've seen, either very good or barely different from pre-op.
