It is not nearly as likely to choose a lemon line as it is when it only has frequency or whatever to go by, which is wrong plenty of times... IE I consider 'crafty' to be an 'entity' comprised of the engine, the gui, the books, the tablebases, and the hardware. Just because it is possible to use some other book, doesn't necessarily mean it is a good idea...
