Well, I#, left handed, and because most things in this world are designed for right handers, left-handers find it easier to adapt to right handed techniques. So everything that i learn, i will do in one stance at training, and then practice it in another stance when i get home. Harder than it sounds, and it sounds hard, but eventually, you'll get used to it, and it will become much easier to adapt to anything with your other hand, not just MA.

Its important to be equally capable from either side. However, not only will having your strong side forward give you an offensive advantage, but also better defensive ability, IMO.

I'm a righty and I stand south paw...my right hand is faster and stronger so I like the think that it can block and intercept attacks better than if my left was in front. Since its stronger I can attack from a shorter distance too and the extra distance I give my left hand gives it some more power. Kicks for me can come from either side, though my right kicks are obviously better. I want my left side to be as strong as possible so that theres less of a difference btwn my right and left. Sometimes I switch to orthodox just to make sure I still got it, or if I really want to give my opponent some extra power with my right. However, I naturally feel more comfortable with my power hand in the front. I might be because of the kungfu or JKD or something, but its natural for me. Same with snowboardings, I ride goofy (right leg in front).

It depends on how the opponent stands. Southpaw I am quicker and counter offensive. Orthodox I plan to be more powerful and offensive each has it advantage and weakness knowing yourself you can work toward your strengths.

Unfournately there are some techniques that I don't do well on my left side, on my right side I'm more versitle. So my trad training of trying to do everything on both side failed but at least I know whats possible and all the KISS stuff I can do well on both sides. So it just depends on what or whos in front of me. I'm comfortable and can change in a second to go either way.

I also find that a lefty is not that hard to fight as it is in boxing in that we train to expect either side and we don't stay in punching range exclusively. Which is in mho were they may have an unexpected advantage.
