KLEM, you are correct.
First; I thank those who believe I know so much but I am given way too much credit for my small contrabution to the sport. Most of what I know about lines, two handed rods and casting I learned from Jimmy Green and Al Buhr. Bob Strobel and Harry Lamire showed the epoxi (super glue) spice.
Though I fished the same waters of Northern California as Jimmy Green in the early days, I never met him until about 1990 when I started fishing the Snake River near his home. We soon became close friends. Though Jimmy had many friends willing to get involved, Al and Jimmy worked most closely design rods, reals, lines and spey casting styles. It was Al and, I believe, Dale Knoche who made his rod building equipment. This is why Al Buhr is the one person I can think of at the moment that could answer all the questions in this discussion.
I was pulled in to the "spey" group not long before I met Jimmy by some of the greats too mumerous to mention. But is was Jimmy and Al, who realy got me interested in the equipment and Al that most influenced my two handed casting. I know that Goran Andersson impressed Al and Jimmy. Jimmy talked about his early years in California when he made lines, as a manufacturer, and successfuly experamented with shooting heads. That would have to have been at least 50 years ago. I would watch him cast which is what got me interested but I couldn't afford the equipment then. I tried but the sticks I had, which included a car radio antenna, just didn't get the gob done.
See you on the River.
