While visiting the shop yesterday, I learned that one of my young co-workers, recently back from college, would be teaching an even younger group of students how to cast a fly. I’ve always found my friend’s enthusiasm for fishing contagious, his willingness to help others admirable. Since I’d worked with him in prior years on the principles of casting, I thought perhaps the moment was right for a brief refresher. I grabbed the shop’s practice rod and made several casts—casts where the line rolled out in a wide, sloppy loop, with line tip and leader collapsing in a pile at the end. I asked my friend to analyze and solve this problem, so that my ensuing casts would straighten out. (The inability to cast a straight line, on demand, is one of the most common problems in flycasting, afflicting not only beginners but often those of us with many years of experience. How to cast a straight line is one of the first things we should all be taught.)
After thinking it through, my friend concluded that my casting stroke was too long. He said I was taking the rod too far behind me on the backcast. “What should I do?”, I asked. Boldly, he replied, “Stop your backcast at 12:00 o’clock”. So I did. And my next cast finished by slamming hard into the floor, line tip and leader piling up again, albeit with authority. I repeated the cast. Same result—my line drove hard into the floor without straightening out. I looked at my friend. Not expecting this, he seemed unsure exactly how to proceed.
I stopped the exercise. I told him that his analysis was correct—my stroke was too long, I was taking the rod too far back on the backcast. But even as he had correctly diagnosed the problem, his proffered solution—”stop the rod at 12:00 o’clock”—condemned my casts to failure. Here’s why. The length of the casting stroke is a function of the length of the line. The relationship works like this: Short line, short stroke. Longer line, longer stroke. So every time we change the length of our line we also change the length of our stroke. Consequently, there can be no fixed backcast position. The correct backcast position varies depending on the distance being cast. Could be 10:00 a.m., high noon, 3:00 p.m., or any time in between. In my case, it turned out the right position was about 2:00 o’clock. That resulted in my line turning over perfectly, straightening out just before it settled gently to the floor.
My friend ultimately came to realize that he had offered up a stock answer to a problem with infinitely variable answers. When faced with this same situation myself when teaching, I said that I find it more productive to simply ask my students to not take the rod back so far. By not verbally specifying a particular “time”, but instead watching the line itself and adjusting to its behavior—lengthening or shortening the stroke, as required—students find the correct backcast position simply by feel, ingraining that position in their muscles as well as their mind.
Good flycasting instruction requires concise, thoughtful communication. Knowledge alone, while necessary, is never enough. In time, my friend is going to make an excellent teacher. I respectfully suggested to him that he continue to refine his delivery, learning how to say exactly what he means, and learning to recognize when he isn’t. That’s not easy, but it’s one of the things the best instructors always think about, one of the ways in which they stand apart.
