i've been watching his videos on Faceache and have been trying the techniques out on the range and around our 9th green before i go out and play on the course.Been working on the Dan Grieve short game over the weekend and so the release 3 for the flop shot is starting to come into my arsenal. It does require a decent lie (so not likely on our sodden courses) and faith and is a work in motion. To be honest the release 2 has been a powerful short game tool anyway. I've always struggled with a LW and so it hasn't been in my bag for years. There aren't many occasions where a player of my level would need to play this shot and do so properly
not sure what "release" it is but you basically stand close to the ball (toe down) and have the club back in the stance and swing across with very little hinge.
