Tried the tornado guard today.
Roleta's grip, thumb down, works better than Cyborg's, thumb up, on the collar. It helps me break down the opponent and feels better when going inverted, because your arm is in the "right" position.
Now to the fun stuff. I worked this on lower belts who are my size or smaller. It worked fairly well on those. If the person is about the same size it will work.
On bigger guys, it is just impossible for me to get that leverage for the sweep.
They would have to really bring their head past my hips and make their feet light.
I ll keep on playing with it and see what else I can find. I think that its in an interesting setup, because I look for the underhook while in half guard, or look for the deep half guard.
If the person on top is sitting heavy on his leg and keeping his elbow closed, the tornado guard would go against his other side, which could facilitate an opening at least.
Just as a reminder, your heel will dig pretty good into the guys balls if he is not wearing a cup, so people can get fairly pissed off about it.
