Hey Mike,
as a fellow kenpo guy, I'll go back and quote Mr. Parker. I'll actually try and suppress my gag reflex, because I really hate it when people do this, but in this case I think it's appropriate.
How many people like to point out that Mr. Parker said something on the lines of, "I'd rather have ten good techs that I can really use, than 100 techs that I can't use"? People quote this all the time, I can't count the number of times I've seen this in the kenpo threads.
Sometimes having too many systems in the mix, too many partially understood arts thrown into a hodgepodge, is like having 100 techs that you can't use. You end up ignoring, or not giving enough training time to the 10 that you can use.
I'm saying this as someone who has also trained several different systems. Much of what I've trained I've also let go, because I came to the conclusion that it's not right for me. I still train a couple of systems, but I'm very careful about spreading myself too thin.
Good points Mike.
Now, seeing that we're both Kenpo guys, we both know that there're enough techniques in the Parker and Tracy system to last 20 lifetimes. So, while I agree with the saying, "I'd rather have 10 that I can do, rather than 100 that I can't" your 10, my 10, and everybody elses 10 will all be different. So, the result is learning the entire system, and picking what works for us.
IMO, I think that alot of times, when people talk about crosstraining, the first thing that comes to mind is the time...how can one find enough time in the day to train 10 arts. Well, I'm not like some people, who shall remain nameless, who have a laundry list of arts and ranks to match.
There are a number of people out there, who train 1-2 things in addition to their base. As I said, and continue to say, for myself, I'm in no rush. I work 40hrs a week, sometimes more, depending on OT, work a 4pm-12am shift, so my class room time is limited to noon-time classes, privates and training on my own. I do my best to always give it 100% when I'm training. I know the entire Modern Arnis system, as required by the org. that I'm a part of. However, I'm still a student, and even with that, I have my favorite things to use, just like in Kenpo.
If I were to talk to a boxer about training, chances are, I probably would not join up for lessons. But, if there was 1 thing that I could take, drill the heck out of, and end up making my jab that much better, I'm gonna do it.
Like I said about BJJ...I'm no master, I am not ranked, but, I know the basics, and for me, I'd rather have that, be effective with that, than be a fish out of water, should I end up on the ground. Can I tap the guy who I train with? Not a chance. Will I best Leo Gaje? Not a chance. But the average punk isn't on their level. I try to be the best that I can, and train for the worst case.
So, what is too much? 1, 2, 3, 10? Looking at some past threads I've started on mult arts, I'd asked that same question....how can someone train 8 different arts, and have 6th, 7th and 8th degrees? I'm not in it for the rank...never have, never will be. I just love to train.
For the amount of time that I've been doing Arnis, one would think I'd be a higher rank than I am, but thats fine.
With the exception of BJJ, which getting back to class is part of my New Years plan, every Kenpo person that I train with, is ranked in Arnis, so I'm always training something.
There are a few other things I'd like to look into, but I dont kid myself. With my current training and work schedule, in addition to not wanting to neglect my wife, by running out to train on my nights off
...I stay content with what I do.
Sorry for the long rant. I hope that answered some of your questions.
Have a great Holiday!
Mike
