Query: Disappointing collection of unknown patterns

This book should have been subtitled, "Let's get the gang together to create a book of all the patterns we created at the bench." It has few of the real standards and way too many flies that no one has ever heard of. I was hoping to have a reference such that if I discovered a new fly, I'd know where to get a pattern. I have owned this booked for a year and while I have often looked though it, I bet I haven't tied 5 patterns it contains. Save your money!
