Thanks, Twofly. It is true that I, and a few of the folks I used to fish with, used "sighters" long before I'd ever heard of Euro-nymphing or the term "sighter" For years I just called them strike indicators. Like I said in the article, the credit for the idea goes to others, not me.
For the most part, I use one leader formula for most of my fishing with the leader. Formula starts with 20 lb. test fluroescent blue stren which mics out to .018", not 30 lb. test. I do alter the formula at times especially when I go to fish small mountain streams. This is easily accomplished by using the 60-20-20 rule for leader construction.
