I personally don't do too much "reality training". At this point in my life I train strictly in aikido. I have been for about 12 years now.
I started Shotokan karate when I was 15 years old. That was 30 years ago. Even as a young guy, I was always getting hurt...shins, elbows, feet, ribs, nose, etc...
I welcomed aikido's philosophies and way of training. Personally, I have no problem separating the arts. I also got a little rank in Tae Kwon Do.
Personally, I try to make sure that my aikido works.
This is what I do. I have absolutely NO PROBLEM with anybody else integrating their other martial arts. I run an aikido dojo and I teach strictly aikido. When people from other arts train with us, they sometimes have questions on how aikido would work in a certain situation. We stay together after class and work out those scenarios. I show him how I would handle it in aikido, Tae Kwon Do and Shotkan. They show me how they would handle it in their style. I have learned many things from these people and I would think that they from me.
You know, it's not a competition to see which art is better. I really do beleive that it is better for someone to get a solid foundation in one art, rather than trying to learn 3 or 4 arts at one time.
I respect each of your decisions on how you wish to train. I would hope that you would respect mine.
