A sinking line requires more experience to cast, but can result in more fish at the end of the day, as trout often take to deep water (especially if it is sunny) and can feed out of reach of a floating line. If you are boat fishing on the drift, it is often necessary to use a very fast sinking line to get your flies down deep enough to catch. Each sinking line should indicate a sink rate in inches per second (IPS).
