I think southpaw is best when you're smaller n quicker. But if you're bigger or stronger, you should fight orthodox.
Fight in whatever stance is best for you. Victor Ortiz is a right handed guy and fights southpaw.
However you're comfortable with. It is of your advantage because you will be throwing heavy jabs as I assume you're right hand being a natural righty punches harder than the left.
Do what is more comfortable and natural for you.
If your right is your best hand this can be an advantage in that your jab and hook will be better than using your left for those punches.
Just like when all lefties were converted to right hand, they had good left leads but not always power in the right.
If you're right handed, stay as an orthodox as you'll get used to it. Your read hand is meant to be the more powerful/dominant hand and if you have it at the front you'll be a 1 handed fighter
I'm a righty and people say if you're a righty, you're supposed to fight in an orthodox stance and if you're a lefty, a southpaw stance but I feel more comfortable, faster and more advanced in a southpaw stance. Can I continue to be a southpaw or do I have to try to get used to being an orthodox? Any tips?
