No doubt he has put in some time. In the first form he seemed "shakey" on the slower high kicks and a few of the other higher flexibility/strength movements. Regardless of how well or how poorly the forms are performed, I wouldn't use them in combat. The Dragon form was more wushu than actual combat effectiveness. Clearly meant to impress the type of person who equates acrobatic ability and flexibility with actual combat effectiveness. I have the same criticism with B-Boys. Crowds love the g@y sh1t that isn't really even dancing and get bored when they see real footwork. While the educated drool over a nice set, average folks just wanna see dudes spin on their head and do handsprings. C'est la vie
Many, if not all, arts have this problem.
The beginning of his dragon form reminded me of how B-Boys look when they are learning. They are getting it but just aren't there yet. Like at a low intermediate level looking to move into the higher intermediate ranks. The truly fresh B-Boys look smooth all the time. They are so good that even when they fukc up they make it look dope like it was their plan all along. Recovery is one of the most important aspects. To stand there and try to remember what comes next is considered rookie sh1t and I have seen Sin The do that.
But this guy is a black belt and was the sponsor of the tourney. Probably runs a school, right? I just expect more from somebody who calls themselves an expert or master. Cleaner transitions, solid flowing movements etc. You can find children doing better acrobatic "shaolin" forms on youtube.
I wish my Sifu was the type of guy who lets others film him. Alas, he is beyond humble and only really gets loose behind closed doors. Once accepted as a student, it's just a matter of time before he does something to make you do the open mouthed double take. On the street you would think he's a harmless little man with a confident friendly disposition. He doesn't make bullsh1t claims because he doesn't make any claims at all. There are no d1ck enlarging stories of greatness. No insecure lies in an attempt for legitimacy and consumer appeal. Take it or leave it. He runs the school at a loss cause he loves Kung Fu and wants to help anyone he can. He is not unique, by any means. There are tons of Teachers like him. Just depends on the research.
