Cross Guard Variation Part 1

So, watching Rodrigo Simoes work the old school cross guard this past weekend on Zak Maxwell got me thinking about the differences between that and the newer Robinho/Cobrinha style cross guard. I find both to be very interesting and effective guards that take some getting used to. With that being said, I figured I would put up instructionals for each. Here is Pe de Pano demonstrating how he plays the guard. Next I will put up a Robson Moura intructional. Feel free to discuss and let me know what you guys think of these different variations.
