This isn't a dig. This is the truth. How can a person tell you about the mechanics of playing the piano or guitar if that person doesn't practice or play the piano or guitar. How can a person tell you about the mechanics of swimming in the ocean vs swimming in a pool if that person has done neither. How can you tell me about something that I train and actually use. If you don't train or use what I train? So if this takes away the debate then, good. Because it shouldn't be a debate. It should be a discussion. If you like straight punches then good. That's great. I like linear punches too. I mix things up and I can use both with no problems. But during this conversation, I and others have given you more knowledge about circular punches than you have given us about linear punches. It would be arrogant to think that I could grasp something that I don't train. Especially when it comes to martial arts, where so many people train martial arts and still can't grasp stuff.
