Fly Tying and Fly Fishing for Bass and Panfish by Tom Nixon is a great book. One that can help you see the progression of fly tying for warm water species. I became friends with some folks that knew Tom Nixon and were members of the same fly fishing club.

After Tom's death, I participated in a couple of memorial fly swaps. Just thought I would throw out a few links that show a few of Tom's patterns from a fly swaps.
