The top clip is an excerpt taken from an old mendes bros dvd. I have the no gi section of the dvd which is about 20 min long. It covers about 10 techniques and then shows a grappling match in japan, in which Rafael competed in. As far as the name, no clue. It's in japanese/portuguese.
I know you can hit all of these leg ride rolls with a basic leg hook but it's funny that nobody but Eddie utilizes a lockdown grapevine on most of them.
I actually popped my knee once on a capoera pass to quarter guard to single leg ride roll to back control because I didn't get my knee in deep enough. I was okay but mid roll I felt like I was on the brink of twisting my knee sideways because I wasn't thigh against thigh when I dove for the roll. It scared the hell out of me and now I make sure I'm deep with my leg hook if I want to roll without a grapevine.
I believe they just plan in launching the Mendes Bros Online instructional site sometime this year since they are now teaching in CA. I don't think they have any DVDs down the pipe. If it'shalf as good as Mginaction I'm sold.
