50 metre spool of Fulling Mill Masterclass Copolymer.
When fish are high in the water feeding on emergers or dry flies, Copolymer is certainly the tippet material to reach for.
Copolymer has a lower density rating compared to that of fluorocarbon, so it sinks at a slower rate allowing you to present your flies higher in the water column for longer.
As a rule of thumb, whether they fish rivers or lakes, many anglers tend to only use Copolymer when dry fly fishing.
Copolymer is extremely supple and allows your flies to drift freely on the water surface without too much surface tension, much like the real thing.
Competitive anglers have shown the advantage of fishing nymphs and buzzers on a method called ‘the washing line’ where they want their flies to hang in the surface film throughout the whole retrieve.
