The subject that created (probably) the greatest "regurgitory" reflex response (upon myself) while listening to these peoples lectures, was their ability to completely walk around how (they insist) to properly apply a (meaning any) tuite technique.
I will say, they have quite the racket going on though. The most prominent of these groups (“Kyusho Intl.” WTF is that supposed to imply?) has convinced a lot of sucker's with their nonsense. Not that they (probably) can't make a fair amount er,...well, some of it, uh, somewhat work (well,... at least create a result).
