This is my first visit as a logged on member. I view this site however,at least once per 'new panfish article' from Rick Z. I have built a few flyrods back in the "Herter" days so you can see how really dated I am on this subject. Now after this intro,I have a question on rod building: What type,name specific,does one use to mark the wt of the line on the rod? Do you use a sharpie,or some other pen?? Thks, pw.
