I agree with TigerWoman concerning humility. I believe that humilty and the pride of life are opposites. I take wearing a uniform with these accomplishments posted all across the back lacks humility, in my mind. Shu.. Why are you on the fence as far as championship uniforms? Why would you feel weird wearing it? Of course this may be offensive to some in the ATA, but I also feel the Grand Master, and all the others wearing all those bright colored gi's is also lacking humility in my book.
I personally feel that there is nothing wrong with pride, as long as one does not take it too far. Just like anything else in life. Be proud of what you acheive, but be humble about it. Someone may earn a World Champ title and they can, and should, be proud of that. They put in the time, sweat, blood, and sacrifice to earn it. However, they need to realize that there is always someone better and that title is not the end-all, be all.
I am on the fence with the uniforms because of that. I personally would not wear the championship uniform, but I would want my students to wear one. I want to recognize their acheivements and their hard work. To me, they won't be saying "I am a bad ***", but rather "with my hard work and dedication, this is what I can accomplish". When I spar against a World Champion, I don't think he is bragging, but when I see that uniform I know he is a serious student, hard worker, and is dedicated.
As for the ATA colored gi's, those are only for the ceremonies. When working out, teaching, or otherwise they wear the same exact uniform that I, a 2nd degree, wear. Plain white uniform with 4 judging cheverons, instructor collar, ATA patch on the chest, and bb/MC patches on the side. I have no problem with the colored uniforms for our ceremonies because it distinguishs the level of mastership of our art. It has nothing to do with lack of humility- it is to show a seperation of rank and knowledge.
And no, I will not be teaching XMA, for reasons that I stated. Even if I wanted to, I don't practice those "fancy" techniques to the degree to get THAT good at them. Heck, when I spar I don't attempt any jump kicks, 1 or 2 spin kicks, and a handful of high kicks. It isn't that I can't do them, it is just that in 15 years everyone I compete against won't be able to do them "well", myself included. I just stick with what I will be able to do well my entire life.
