How do those of you who own a rotary vise use the rotary feature? What types of things are more easily done with the rotary vise? What things could not be done without the rotary feature? Any real cool things? Do you half-hitch before using the rotary feature? Even though I just started fly tying recently, I ended up with two vises, a Danvise and a Griffin Superior 2A. I bought the Danvise first, but I couldn't pass up the Griffin for the price (it had been sitting on the shelf for a while). So far, I haven't been able to find anything about how to use the rotary feature on any rotary vise, Danvise or otherwise, so I ordered a DVD from Al Beatty (Rotary Tying Techniques). It seems that if I'm not going to use the rotary feature, I'd be better off with the simplicity of the Griffin. I'm thinking I might even sell the Danvise, but I'd like to know more about how I might benefit from using a rotary vise before doing something rash like putting it on Ebay.
