I came across both of these websites a while ago and they have provided me with some really great insight, information, and fly recipes. The first is a website by Dave Whitlock devoted mostly to bass and panfish. It contains a section on different categories of flies, as well as the recipes to make them and detailed step analysis. There is also a really great section involving east-to-make fly tying tools that can really come in handy. The second site is a great resource on the nature of bass and how to go about targeting them. Just thought I'd share both of these as they have helped me a great deal.
