Ive probably got the minority opinion on this one. For the most part it is a fantastic book, filled with a ton of good information. When the book talks about position routes however, I have some issues with it.
He breaks everything down into what he deems as C player, B player and A player levels of play. Some of the position routes he lists in the A player section are not reasonable high percentage shots for anybody but a select few players in this world. He takes examples from the pros in tournament competition settings and uses what they did as to get out of very tough spots as routes that you should know. IMO there are multiple cue ball routes in there that are far more complicated than the safes that should be shot in their place.
