The quality and length of the segments are excellent and they come across great on my computer unlike so many things on the internet. I really like what he says (in the english interpretations) and have learned some really cool moves from watching him.
Shishiya Sensei is truely one of Nishio Shihan's better students and is known for his big flowing movements. Those vids were a joy to watch and a good reminder of the practical application of Aikido's philosphy. A tiny quibble for me would be that the Uke's were dead looking down at thier feet poor posture and letting thier off hand flail at the side instead of bringing it in to the chest ready to strike. If you're using those to study Jorge you might be mindful of that.
I see you are down in Tejas and if you're interested we do have a Nishio affliated sister Dojo in San Antonio.
. Drop in if you get the chance.
