Greg Mele, of the Chicago Swordplay Guild, has written an article that describes what I consider to be the best way to approach out art. We will never "do Fiore's art" - we can only use Fiore's principles and concepts to do our own version of that art. Heck, I don't even do the same art as my instructor. Really, really, really, really (x15) similar, but not the same because our bodies are slightly different and we have different backgrounds. Great further reading for this is anything Bruce Lee wrote about Jeet Kune Do - ground yourself in Principles, but adapt techniques to your abilities.
