julio diaz and courtney burton where two fighters that where known for switching their stance in many of the rounds of their fights. it was a real treat to me when they actually got paired together to fight, in a very action packed fight which both where switching stances in the fight. i think the two supermiddle weight andres' ward and durell can fight both styles effectively.
Nonito Donaire is getting better at his south paw stance. Against Herman Marquez he fought the first 4 rounds as a south paw.
Andrew Golota had some good time switching to a southpaw like against Bowe or later against McBride. The fluidity of that moves shows how skilled Golota was and how big waste of talent he is.
