Tippet rings are a great way to extend the life of your leaders and tippets. Very popular with Euro style nymphing.
A leader with a tippet ring turns over perfectly. Use lightweight Tippet Rings when fishing dry flies. Just tie the tippet ring to a leader with a clinch knot, and then add the required tippet in the same way. Tapered leaders last longer with a tippet ring since the leader isn't shortened every time tippets are replaced. Tippet rings also make it amazingly simple to add droppers. Th
