This book has a number of unique or different ideas on how to tie a particular fly or part of a fly. It's really not a "production" fly tying book. It's more of a fly tying book for those who have some familiarity with fly tying. The ideas are very practical and can be performed by intermediate tyers. I would not recommend this book as a first or second fly tying book, but it is a great book for someone who has done some fly tying and wants a different perspective. Frankly, a must read book for fly tiers.
