Yes. Excellent insight into leg locking theory/concepts. Very verbose in Danaher's special way. Current version has poor audio, but they are re-recording it to fix it. Even though I have a lot of leglock instructionals (MTS stuff, Craig Jones, Rob Biernacki, etc.), each one brings new info and/or looks at the same thing from a different perspective. I felt like Danaher's tied it all together.
