These smooth, high quality rings will save you time & money as you don't need to keep replacing shortened  leaders on the river. Instead of constantly shortening your leader as you change flies,  tie one on the end of a 7 ft. 3x, 4x, or 5x leader, and then add whatever tippet the conditions call for.
Additionally, the micro tippet ring is a great anchor spot for your split shot or putty weight.
