I have Marlos RCT and its one of my fav books. Its always being picked up out of my library. The Faro Chapters alone is what was worth picking up for me.
The Second, Centers, and Bottoms is awsome.
Marlos material ranges from the easy to the knuckle busting. The practical to the impractical. RCT is a great book IMO but it requries dedication as Marlos works reads a little dry.
Kind regards,
Mike
