Quick Summary
Drennan Fluorocarbon Fly Leader Line is a 5lb fly leader line supplied on a 50 m spool. It is described as fluorocarbon with a refractive index very close to water, and as a line that is almost invisible to trout in water.
The same product is also described as having very high knot strength and high abrasion resistance, so the main buying checks are the breaking strain, spool length and whether a fluorocarbon fly leader suits your setup.
