You gotta vid so I can tell if we are talking bout the same thing? I saw it a long time ago and I'm going off an old memory. I have done things similar in other styles, but they were a bit different than what I'm thinking of. The ones I learned didn't use the shoulder striking but still drove in under the same principles. Leg sweep, hip toss, hook up and turn the corner for a double even. It's the strike that interests me, not the takedown.

It may have been 8 step. It's been awhile.
