Yes to all you wrote. But what I'm noticing is that you get the same from the Karate knee strike, but with more power. There's a slight advantage for the MT/MMA technique in a body to body clinch. But even that's negated by being able to manhandle the opponent to where you want him, then using a roundhouse knee.
So I'm still left wondering why sacrifice the power?
Just when you think something is foolproof, they come out with a new and improved type of fool.
