well im a left hander and im a south paw but im only a new amature boxer myself. i guess whatever you feel the most comfable with then do it. im a south paw , i wirte with my left hand but i strong foot is my right ,which is my power kick in soccer and when i play cricket i bat with my right hand even though im left handed . So im guessing boxing is the same whatever you feel the best with .

seriously man i donno if that made any sense to you or even helped you lol .
