This is unquestionably the best sink tip line I have used. I have used this in a variety of settings from rivers, still water and warm water. It performs every time. Cast remarkably well and shoot through the guides. Very easy to cast in the "key range" of 30 ft of line. I use the Sink 3 which drops at a rate of 3 inches/Sec. I have found this rate to be the most versatile for all settings. Using a fast rate of retrieve will allow your streamer/fly to stay sub-surface and graze the middle of the water column where fish are holding. A slow rate will allow you to graze the bottom and you can easily throw in a pause to entice a strike. In deep still water settings, allow a pause on your cast to reach your required depth. This line is incredibly strong and is built for abuse. With some very minimal care, this line will last for many seasons of fishing. If hucking meat is your game, this line is the ticket!
