Cortland Kelly Galloup Rock Bottom Sinking Line
Kelly Galloup designed the Cortland Kelly Galloup Rock Bottom taper to excel in medium to large rivers where you need to cover distance and depth. Featuring an extended 40 ft Type 6 (6–7.5 inches per second) sinking head with an intermediate running line, this line is meant to keep your fly down in the zone for the entire retrieve. The overweighted head loads modern fast-action rods quickly and shoots large flies with minimal back casts. An oversized running line improves handling and extra grip for driving home strip sets. Featuring our new Reinforced Tungsten Technology, made from the highest-grade tungsten materials available, this is the most durable sinking line ever created. Line ID is printed on the running line for convenient reference.

This line performs well in deeper rivers. The sinking rate is consistent and keeps the fly down where it needs to be. The extra grip on the running line helps with strip sets, and the tungsten head loads the rod smoothly without back casts.
Edward Turner –
I’ve used it in several medium to large rivers and it holds its depth well. The handling is better than previous lines I’ve tried, especially when casting large flies. A bit heavy for short casts, but ideal for long retrieves.
Colin May –
The durability stands out. After several weeks of use in rough conditions, there’s no sign of wear. The sinking head stays stable and the line doesn’t tangle easily during fast retrieves.
