oh i dont know i did tai chi for about 7 years with a few guys who had studied it for over 2 decades they were pretty good but not well known masters, but hey it gives me a reference point right.
Now the question is how much grappling have you done with top level guys, how many competitions have you done so you have a frame of reference when you talk about not needing to use strength in tat setting....how much extenral training have you done so you can actually compare the two and decide which is superior
