Dan Frasier's new book is a must have for anyone interested in chasing carp with a fly rod. The book has a great data base of flies and Dan goes on to break down when and where to fish the flies. Both Zach and Ben have patterns displayed in the book Zach's Wizard Sleeve and Ben's Bottom Creeper. I just picked up the book Friday (and on Amazon it's <$10) and read it front to back over the weekend. I would highly recommend it and at $10 you don't have much to lose. There are a few tips I can't wait to give a try when it warms up.
