The best guy I've seen at switch hitting regularly is Andre ward. If you have good coordination and the right core principles in your boxing the only real change is the angles you have to work with, both stances have their advantages, but most guys don't apply the same pressure both ways. There is a slight shift in their mentality. Like Marvin hagler against Leonard in the early rounds. He thought of himself as more of a boxer in the orthodox stance and it
cost him early rounds.
