meh. You'll find better stuff in MT and Sanda. I like the first two entries and sweeps.. the last one is interesting, but I don't think I don't recall ever seen it being pulled off and it is a bit extravegant. The one where he switches hands on the kick catch is a waste of time to me.
I'm going to agree these are pretty meh actually. The Muay Thai style sweeps there are much better setups for and the Kickboxing style sweeps are illegal under Full Contact Rules from what I recall when I competed (instep to outstep with the foot and below the ankle only).
You should move away from your opponent's back hand and not move toward his back hand (at 6.32, 7.06, ...). It's risky to move into your opponent's back fist punching range.
The first ones were all fine. Stuff I've learnt and done. The last couple were a bit more WKSA specific.
