While a lot of it looks like other systems i've familiar with (there's nothing new under the sun) they've put it together in some innovative and impressive ways. I'm interesting in seeing more......unfortunately, living in Missouri, I have to wait for everything to filter out from the coasts unless I travel to LA or train by video.
A lot elbow use......we did something similar years ago, we were even doing elbow strikes on the speed bag.....but we just kind of stopped developing the different angulated strikes. Perhaps it's time to dust them off and reexamine them. Kind of reminds of a 'Chris Clugston' video I saw the way the elbows are used.
