Question? I do not have any instructors near by but have been looking at You Tube at this kata. Several black belts have a similar kata's posted ( from Holland, Russia, USA, Canada, etc). So the pattern is similiar, then I stumbled upon a version that an okinawan master performed in 2009. He left out parts ( I have heard they do this in public performances for a reason). The main question is in the kata, it shows a up flip of the tonfa, followed by a down flip and cross swing several times in the kata. The Okinawan Master Nakamori-san does his a swinging flip up with both tonfa at the same time (two revolutions)- see also karate by jesse on you tube. Similiar to the one hand at a time in Matsu higa no tonfa. My question is which to follow? Nakamori san is harder to do, so is that why some modified it? Can anyone shed some light on this? Thanks
