I have been wondering about the origin of the skagit line system of spey lines. Many years ago i went on a trip with Dennis Dickson on the Skykomish. He showed us a shooting head system he developed for single hand rods. Basically you buy a regular WF line, cut about 10' off the tip and however many feet off the back end to get a head of about 30'. Attach this to a running line (back then he used a flat monofilament line made for spinning rods. With this system you simply make one back cast and the head can shoot up to 80-90 feet! I still use my own homemade system with a sage rpl 690. But now RIO et al make us pay over 100$ for something you can make yourself!
