Man oh man the guys at tightlinevideo make some really nice videos. I bought some furled leaders from Joe Sanders (Lotech Furled Leaders) and had him attached tippet rings as an add on. I have never heard of tippet rings, but thought I'd give them a whirl.
This video shows the virtues of using tippet rings. I like the fact he shows how to attach the rings and recommends changing tippet material often.
Give Lotech Furled Leaders a try. Joe sells them 3 for $10, or 3 for $11.50 with tippet rings. Mine should be here next week.
