Hi Phillip,
I teach/train WSLVT as well. My favorite quote of WSL was "Don't be a slave to the system", that tells me allot. Since hearing that and having the ability to train in his system, I've come to realize that VT is just about training, creating good habits, correcting mistakes, building structure and mechanics. The vast majority of the training is two man drills with prolonged contact, anything outside of that for me is just training timing, distancing and perception, so for me the sparring in those vids is outside of the VT training IMO.
Just so you know, I wasn't knocking the VT guys performance, he had great punches, structure, was fast and powerful, it is just the timing of it all, but if that was something specific being worked on then I can see your points.
To me it's all about being natural, the training has to effect your natural responses, make things tighter, more accurate and powerful. I just see too many video's where VT people are trying to display the style, the things they do in training, which creates robots and mechanical movements. If there's no bridge contact, no one should know your a VT man
