I know this is digging up a very old thread but I lived in Warner Robins, Ga and my daughter and I trained under Master David Barber. I can tell you for certain he is legit. He was a master in many different disciplines. He was amazing at Muay Thai; he used to let us break bamboo canes over his shins and he wouldn't even flinch. He's only about 5'4" tall but he kicked a ceiling tile out in the dojo one night just to show he could. He could hit you so fast you would not have time to even react and that includes kicking you in the face. I've seen him in many fights and regardless of who they put against him he made them look like chumps. Most of the time he would string the guy along so the crowd would feel like they got their money's worth but he could take out anybody in the first 10 seconds if he wanted; he was just that good. He was an amazing teacher too and trained other world champions. He is on Facebook and you can see some of his creds there.
