Many people believe that all fly lines are pretty much the same. Fly shops have dozens, maybe hundreds, of different fly lines to choose from. This lesson is a tutorial on how these fly lines differ and how picking the right fly line for your rod, your casting style, and your fishing can make a huge difference in both the enjoyment of your outing and in the success you have. For instance there are many significant differences in weight forward fly lines. This video describes the four parts of each fly line and the materials used. Different conditions, rods, and personal preference often dictate which line to buy. I personally believe that virtually any rod can be made to perform well if it has the appropriate fly line.
