Don't let go of your perfect double unders to lift yourself off the ground. I find that when I'm in lockdown. I don't wait to show them what I'm doing right away so I t-rex my arm that he can whizzer and the other one hooks under his leg like I'm going for an electric chair. Mixing these two together (Electric chair and dogfight) will increase your success rate of both. and if you add in a nice transition to prison guard from there, then you really start noticing the difference.
My thoughts when in lockdown are get the underhooks, then T-rex one arm and push them for a dogfight, they almost always resist that so I go to my EC, then I found that they straighten their leg to the side and backwards which stops the EC but gives you an easy prison guard transition. if you get stuffed going to prison guard, just switch back to one of the other two options. or just take the butterfly guard.
You end up either getting into dog fight, Electric side, Prison guard/back etc, or Butterfly guard.
Is that kind of what you were looking for?
