I am sure those techniques work for him.
However, I picked up his book at the local Libary. I have read it and while he has some interesting ideas, most are too "foo-foo" for me.
I will admit that using a foiled brick on top of the meat grill to lean a thick steak or chop against sounds like a good idea. In fact, the raised grill for part of the cook makes sense, too.
All in all, tho', too "foo-foo" for me...
FWIW
