Some anglers think that indicator fishing is Czech Nymphing. It is not. The only indicator used in the Czech style would be a change in color at the end of your fly line. In some cases though it is more like running line.
I did find myself wanting to step back when hours went by without a hook up. Lucky that I left my complement of indicators at home and was not able to fall to temptation. What I found was I needed to be more attentive and far more focused. Feel was as important as sight, I was successful and I felt good. So, it seemed, unless some event were to change my mind, I am going to stay with the program. That event happened. When the water temperature dipped to below 39 degrees the takes were lighter and hardly detectable. And when the water hit 36 degrees the catching pretty much stopped. I did go back to the indicator over the last few weeks with success. I am now convinced that we should use an indicator as the tool that it is and keep it away when not needed.
