On the http://www.globalflyfishers.org or it may be no s and com not org, I can't remember, there was a link to a program called excel viewer. You could view, though not calculate the leaders. May I suggest that you consider purchasing an excellent leader book, from Stackpole books, $24.95, called Drag Free Drift by Joseph A. Kissane which comes with leader-calc on a CD rom by Steve B. Schweitzer. Haven't finished it..but so far it is excellent. No affiliation..just a very happy customer. Joyce
