I can say this relates to firing a pistol or rifle too. I never figured I would have to fire my pistol with my left hand until I got some more fire arms training, it helps out the confidence a lot. So, back to fishing, I had hand-me-down rods from Dad and others, so I didn't get to choose growing up lefty or righty, just learned both, and now it really doesn't matter. I say learn both, it is one more challenge that you can lay on yourself...and conquer!
