Matching Major Eastern Hatches: New Patterns for Selective Trout (Headwater Books, 2011) by Henry Ramsay is a must read for anglers and tyers who ply their craft on Eastern waters. In this treasure you will find loads and loads of highly useful patterns. Tying instructions are clear and well-illustrated with superb photographs. There are awesome, detailed and very captivating pictures of the naturals as well. I had some time at the recent Arts of The Angler in Danbury, CT to chat with Henry and let me tell you he is the real deal with great knowledge. His clear thinking is reflected in his writing. And he's a good guy to boot. Check out his website: www.ramsayflies.com. Read more and get Henry's book at www.bearsden.com/product10475.html.
