Airflo 5ft Polyleaders with pre tied loops at each end. Floating: Ideal for Buzzer fishing to give you greater visibility of takes and closer contact with the fly. Also useful when dry fly fishing where you require part of the leader to float and the rest to sink so that the fish cannot see the leader on the surface. Intermediate: Transform your floating line in to a sink tip to keep nymphs and lures on a steady level when retreaving. Slow sink: Faster sink rate than the intermediate, usefull for river fishing to get nymphs fown in fast flowing water with a short section of leader on the end. Fast sinking: Ideal for deep waters or very fast flowing rivers where you need to get down to the fish. Super fast sink: For very fast and deep river fishing or reservoir fishing to get the fly down very fast.
