Yeah I got it. it's awesome. The guy is a good teacher, and he teaches a lot like Ryan Hall, and I know some people are saying that this is a Danaher leglock system bootleg, but it covers a lot of that stuff but it's more than just that. It's clear that this guy has learned a lot from Ryan Hall, Eddie Cummings, Bill Cooper, Palhares, Dean Lister, Caio Terra, and others. He gives credit where it's due on the instructional and the set is incredibly dense. it's 10 volumes/discs and each volume has 2 or sometimes 3 chapters within that.
It's definitely the best resource out there on the position before submission' style leg locking that has become big in the past few years and the guy knows his shit. The focus is mostly on outside and inside heel hooks, but there's material on there on other leg locks as well. He uses a lot of talk about levers/frames and things like that. It's a very scientific style of teaching. That may or may not be your cup of tea but I find it helpful.
He covers the positional hierarchy. Each of the main leg locking positions. One very simple thing he does is show all the names for each position. There are so many names out there for each leg locking position, and he clarifies them all. He shows mechanics for finishing each of the main leg locks from each of the positions. He goes into positional entries from the bottom and the top. He goes into transitions from position to position. He shows counters. How to deal with those counters. There are sections on mixing upper body and lower body attacks. How to use the leg locks to pass and how to pass a good leg locker. And at the end there are some specialty techniques and scenarios.
