I quite like Super Supreme. I know this because I have tried other styles, and I will occasionally try a different flavour; but when I want something that I know I’m going to enjoy, I stick with the Super Supreme. In martial arts terms; and I know that many will disagree with this, I think we are better of sticking to something that suits our needs. From past experience I have learnt that studying other arts while I train in my chosen art has been counter productive. My chosen art covers a wide range of technical areas. I could perhaps experience these elsewhere, but the techniques wouldn’t work as seamlessly with each other. Further more the principles, theory, and methods of application can be at odds with different arts. So rather than learning a cohesive art that works harmoniously within itself, you end up with just a bunch of techniques that may or may not fit well together well. These are just my thoughts, they reflect my specific experience and are not meant as definitive answer to cross training. I just think that it is worth thinking about these issues rather than just accept the philosophy of cross training at face value.
