Tippet Ring ID/OD?

[fritz]

I'm getting into Czech nymphing and want to know if there are rules of thumb for sizing tippet rings (I.D./O.D.) to connect the 3 lines without impairing the action of the nymphs. Thanks

The only "rule" is the ID must be able to accommodate three strands of tippet. Rings are of course optional for tightlining, but they do make life a bit easier.

Remember that you have to thread these rings so I am not obsessed by using the absolute minimum ID.

I love tippet rings and use them on almost all of my leaders whether dry fly fishing, indicator nymphing, or tightline nymphing. In fact for nymphing, I typically use 2 tippet rings -- one just below the sighter and a second ring above the final tippet section. Tippet rings let you join light tippet to heavier tippet without a problem. They also eliminate many Surgeon's knots which are typically weaker. I have some 3 mm, 2.5 mm and 2 mm rings. I like the 2.5 mm rings for the typical stream trout size leaders and tippets. As others have noted, very small rings can be hard to handle and thread. Larger rings don't really have much negative impact, so go a little larger if in doubt.
