I recently had the opportunity to preview their first CD on spring trout flies, and I think they have a product that's worth looking into if you're having trouble with some of the aspects of tying. The CD has several sections to make it easier to select the procedures you need. It's separated into groups of video clips that show you how to perform each step via a video clip. It also gives you a short introduction to the folks who developed the CD and what their talents and contributions are. It also shows you how to select and prepare the materials you'll be using in the flies you will be tying.
Every step is shown in moving color.
From a tying instructor's point of view, this CD is precise and correct in the details presented. It wasn't designed to do that. It was designed to help you learn from the comfort of that cushy chair you have parked in front of your computer. It was designed to help you understand what the books and series are trying to show you. It does all those things with ease.
