I know we got sidelined, but thats kinda the whole initial point shouldn't it be an individuals choice. Kuk Sool wants to take that away. And you don't have to study a whole system to cross train. You could be spending the hour that you spend training in the gym during the week, instead of doing weights or cardio, learning something from a friend that does something else, thats cross training too. I just find it a dodgy rule. Its probably my perspective of training with people in other arts that say, well this is our idea bring yours we'll test them both see whats best for you and best for me and then decide. Thats what i mean by the fact that to the outside, that rule would "stink of fear" if you are 100% confident in your art (and I don't mean as an individual i mean the association) that it truly is the best you have no fear that if people go look at something else that they won't return to yours. Or alter it.
