traditional martial arts response (long)
Boris_01.........
In some ways i agree with you and others i do not. I agree that it is VERY hard to find an instructor that is able to teach several styles of fighting effectively (ie: grappling, striking, kicking, weapons etc...) That is why i have sought out several instructors.
As for most traditional martial arts coming from thought and theory, strictly speaking, i disagree, having studied history a bit and several styles of combat, i have found that most of these styles (true tradional styles) come from combat experiance, how do you think the okinawans fought off the armed Japanese or bandits, how did the monks fight off raiders or bandits,? it wasnt by thought and theory, now on the other hand, many of these styles have become dilluted to the extent that they seem to be as you have stated.
Ok, next, i fully agree that deep stances limit mobility, but spend any time training in them and you will learn that they have other uses and that they are primarily used at the beggining levels to teach certain things and to develop strength. And as for being linear, some styles of karate are and some are not, and some have both linear and circluar movements, remember you DO NOT have to be right in front of someone to deliver a linear attack, and the quickest way between two points is a straight line. If you look at true traditional styles from history or a good instructor they will tell you that it is almost always better to be "off the line of attack" to attack or counter attack, and every instructor i have had has emphasized that blocks are used as 1) to augmentation getting out of the way 2) to disrupt your opponent 3) to set up another technique or 4) last resort if you cant get out of the way.
Next.....yes some instructors teach that every strike/kick should be with TOTAL commitment, now if you are using an ATTACK TO SUBDUE and opponent would you want to do anything less?! An attack to subdue should be 100% focused on doing what it was intended to do, there are many ways to strike/kick and not all of them are meant to immediatly subdue your opponent, agian they may be used as distraction, set up, etc....as you stated.
The time it takes to learn these nuances and "secrets" of a stlye usally is more time than the average person is willing to commit. Thats why many of these "new styles" are becoming so popular, because they condense everything into a focused regime and they eliminate most of the other stuff in order to give the normal person a quick, "easy" and effective form of self defense.
Now IMOHO a person CAN spend a lot of time with an instructor and learn to be VERY effective in combat, because as i have stated most traditional styles were designed for combat, but to reach that level you must commit for a long time with a traditional instructor/style.
Cross training is a must IMOHO to be 100% READY for any situation. And as you can see a person can spend a lot of time to reach the state of a truley effective hand to hand combat competent person, and in spending that time they will attain not only the knowledge and skill but the physical conditioning to be the most effective that they can be, where-as in a short term self defense class they will not achieve that level of conditioning.
Sorry about the long reply but i wanted to state my response to your "rambling" I feel you had some valid points but not all of your points were IMOHO based on actuality of all styles, more of a generalitzation of the majority of commercialized martial arts training.
Thanks, and btw i did not intend to imply any flamming or bad feelings, just stating my opinion and experiance.
