Double Spey Cast

Here is great video for learning the Double Spey Cast with detail explanation and casting demonstration. It also covers common mistakes and how to correct them. Short of buying a DVD, this is your best bet in learning the Double Spey.

Here is another good video on the Double Spey by Jon of Ashland Fly Shop

ABC of Spey Casting with Steve Rajeff

Here is great video featuring  Steve Rajeff explaining the three predominant style of Spey casting - Traditional vs Scandinavian vs Skagit. If you always wanted to know but do not have the time or patience to read about the differences between the various style, just watch this video and you will be wiser for it. He also talked about why Skagit gravitate towards a deeper bending rod vs Scandinavian preference for a faster taper rod to focus the loop.

RIO Modern Spey Casting Trailer

This is probably a good DVD to get if you want to get started on Spey casting. Watching the trailer, you will get a quick overview of all the various type of cast out there with a spey rod. Some not so common cast being covered are the spiral spey, wombat cast and jelly roll. In the last section, there is good coverage on single hand spey casting as well.

RIO Scandi Short Versitip

Here is a new exciting line from RIO specifically designed for switch rod. For the longest time, my go to line for switch rod is the Wulff Ambush line. The Wulff Ambush line has a nice aggressive taper to it and cast beautiful loops without being clunky, unlike the RIO Skagit short. The Wulff Ambush line is probably the predecessor of a Skandit line (a cross between Skagit and Scandi). From the taper information available from this video, this new RIO Scandi short versitip looks more like a Scandit line to me. The long front taper should guarantee nice clean loops. The head is 23 ft and can be matched to 10ft versitips of various sink rate to cover depth. This line is should also serve well for single hand spey.

Snap-T

Here are two good instructional videos I found on Snap-T. Expertly done and well explained. The 2nd video below is from Vimeo which I am not able to embed here but click on this link >> Link to Snap-T video in Vimeo<< and it will bring you to the video. Enjoy!
