Hi Les. I have read quite a few articles on this line. Most say that it is for traditional bamboo or fibre glass rods. But, lately I have been hearing more and more reviewers say that they have been using it on modern faster actioned graphite rods in light line weights and that it is an awesome line. An aquaintence of mine (unquestionably one of the best, if not the best small stream fanatic in South Africa) swears by it for 000wt-3wt rods. I was thinking of giving it a try on my 3wt, but just wanted to check others views before I wnet ahead and bought it.
Here is a link that may be of interest -
