Some of these knots seem way too complicated for this old guy. I can barely get the tippet through the hook eye once, let alone twice, and I'd have to get out my little reminder card every time I tried some of them! Looks like I might be able to handle the Improved Clinch.

Fritz, I use the Orvis knot for tippet to leader, but haven't tried it for anything else.

Thanks for all the suggestions.
