it wasnt the versatility he had issues with, he didn't like the fact that im good in neither hand ~ switching way too much so that he would even be confused on how to coach me. but im fickle in a way...im still trying to see which hand would be more comfortable.
as i get older i'd use right for certain things, and left for others. i wont say im equally good in every task for both hands, but they do get a pretty equal workout =p
