I agree with MP, if you want to really learn how to fish stillwaters, pick up Denny's books. Denny's lastest book "Stillwater Presentation" is fantastic.
Here is Denny's web site: www.flyfishstillwaters.com - Fly Fishing Stillwaters
Fly Fishing Internet Radio has an episode in their archives where they did an interview with Denny, it is well worth listening to. After listening to Denny speak you will see what I'm talking about and want to get his books.
