A very common problem among fly casters in both saltwater and freshwater situations is that they make a perfect false cast (or two, or three), but when it’s time to let the final cast fly toward the target, everything seems to implode. You might think that’s the fly fishing equivalent of “buck fever,” but legendary angler Andy Mill, points out a simple flaw that’s easy to fix.
Instead of following through with your rod tip as you make that presentation cast, in effect, dropping the rod tip to the water, remember to stop the rod tip high, in order to fully unload the rod and send the line sailing. You stop, then drop.
Dropping the rod tip too soon takes the energy out of the rod. It spoils your casting loop, and cuts down on distance and accuracy.
