I picked up twister side control from his book and use it all the time. I use the twister half guard pass a lot now, and though I'd see passes like it before, the book got me to start using it more to go along with twister side control. I got a lot of twisters, banana splits, crotch rippers and calf crushes from The Truck for a couple weeks after reading the book, but for some reason I stopped. I think I ran into some trouble with setting up the twister roll and decided to work on something else.
I was already doing well with half guard before this book, but started using Old School more and some of the other ones like the Quaterback and Halfback or whatever the ones are called where you go to your knees while still trapping their leg(s).
I get the kamizake calf crush all the time. I try for the Apolo often enough buy have yet to finish it on anyone. I'll go for the electric chair but usually just use it to go out the back.
I use the x-break for armbars every once in a while.
What's funny is that out of all the rubber guard moves, I use the meathook and crowbar the most, and they aren't in the book (just Grappling Mag articles). I'll sometimes pull out stuff like the Invisible Collar, the Duda, etc. but not as much as I probably could (been working on a different style of guard).
It didn't revolutionize my game, but Eddie's book gave me a lot of new material to play with. It was more than worth the $15 I spent on it.
