These Ultimate Clio Backleads are very discreet, glide perfectly over the line and are very easy to use. These leads are often used to let your line run across the bottom as much as possible. This can be very useful in strong current, when ships come by, other fishermen, etc. It also makes it harder to accidentally pick up your own line when fighting a fish. The line is tight on the bottom which makes it very hard for carp to hit. This can also be very useful with cautious fish!
