I agree, there's an abundance of styles out there and while I like innovation I don't see why some create new styles when they've never even tested it. Guys create their own blade system without ever having been in a knife fight. What's the point? Why are you better than your instructors? I read an article recently about how each instructor should tech three styles. The first is the curriculum or traditional system. The second in his instructors understanding or interpretation of that system. And the third is your own understanding and interpretation of your system based on your experience and fights/training. With this approach there is no need to create your own system it's more of an acknowledgement that everyone has a unique understanding and reference for the application of his or her art. I don't teach this way but it makes sense to me.
As far as your thoughts in the person being more important, I disagree. I'm curious if you can explain yourself more in relation to my points. First as has been mentioned each style has potential, it is the method you train that limits you. If all of your training if unrealistic one steps and compliant drills you may never learn what it takes to handle an aggressive attacker. That being said (training method is what limits a person) certain arts and systems all tend to train in the same method, therefore some arts limited by training method. The individual is important, very important and all systems will have good and bad practitioners, but you can be the strongest and most athletic guy in a system but If you only train in compliant and unrealistic methods you're never going to be better than someone with equal drive and motivation that trains in a system that does. A system can limit you based on how they train and what they know, in which case the style trumps individual ability.
Sorry, I haven't been on for a few days, so I just saw this. Sure, I'll clarify my comment. Sure, some systems out there, are probably not as realistic as others. Of course, the person training said style, probably isn't going to think so. But all that aside, why couldn't the student go out and train in a more realistic fashion, cross train, etc? I'll use myself as an example. I've trained Kenpo for 20+yrs. For the record, I no longer actively train at a Kenpo school...I've moved on to another art...but I'll still go through some SD now and then, just to keep things fresh. Anyways, I have a number of training partners who I workout with on a regular basis. Now and then, I'll take some of the things from Kenpo and cross reference them with the arts that my workout partners do. So for example, I'll take a take down defense from Kenpo, and see how well it works with someone who trains BJJ. IMO, the BJJ guy is going to train their take down stuff a bit more realistic than the average Kenpo school. Of course, some die hard Kenpoists will claim that it is realistic, just that I didn't learn it right, blah, blah, blah. Perhaps, or perhaps they're too busy drinking the kool aid, and refuse to take off their rose colored glasses, to see that some things, well...just suck!
Some people will just stick with the unrealistic drills, and never take it a step further. For example: I got into a heated debated with someone who used to be on here, over what is considered sparring, in Modern Arnis. That is also an art that I've trained in for quite a while, and also have a Black Belt in. Anyway, this person was claiming that the stationary drills/patterns that we see in the art, are sparring. I disagreed. Sparring, in the FMAs, IMO, is akin to what you see in the Dog Bros. clips. Oddly enough, all of the stick disarms that you see, which are usually done in a static fashion, usually go out the window, once you're put into a sparring scenario. Things are just moving a bit too fast, for all of the fancy static stuff that you see. But that's the thing...that static stuff is fine...in the beginning, but if you ever want to get good, if you ever want to really test yourself, you need to step out of the box, out of the comfort zone, and train alive.
Trust me, if I knew then, what I know now, about the various training methods, and arts that're out there, I'd have made some serious changes. But it is what it is. I'll give credit where it's due, and I do credit past training, poor or not, because if it wasn't for my initial training, I'd never have been exposed to what I have been today.
So, it's probably a mix of both....a realistic art, and realistic training, on the part of the student.
I hope this answered your question.
