SINKING FLY LINES
Lake fisherman generally prefer a full sinking fly line because the path of the retrieve is level rather than being pulled up higher in the water column like it does on a sink tip. River fisherman prefer sink tips so that they can mend the floating part of the line and control their drift or swing in the moving currents. The most popular lake lines sink at an Intermediate rate which is 1.5 inches per second. Sink tips in rivers vary by circumstance but anything that sinks in the 3-6 inch per second is fairly versatile and anglers will often change the weight of the fly to fish either deeper or shallower.
