I'm not sure I could ever play the other way. My left hand does all the work on both guitar and violin, while the right hand does the dopey work, except when I do classical guitar, they become equal. Though I am right-handed and write right-handed (no pun intended), I am obviously more dexterous with my left hand. If this was the case, then lefties should probably play left-handed, to strenghten the right hand. If not, you're left hand would be agile, but your right hand would go to pot.
