succesful ambidextrous boxers....

It depends on your definition of success.

Hank Lundy is someone I consider to be exceptionally talented as a switch-hitter...very successful in the sense of executing the transitions back and forth seamlessly in the heat of the action, and can fight equally well out of both stances.

Now, does that ability (combined with all his others) guarantee him actual tangible success, as in titles and big money fights? Eh, remains to be seen...given what a basketcase he is, maybe not.

He's probably stuck at ESPN level, but within his level he's one of the most skilled and comfortable switchers in the sport I'd say.
