Nice share.
I don't want to sound like I am nit-picking, but I thought that this site has an article detaling similar knowledge. It may be under the FF101 group of articles Castwell wrote for beginners that is archived here (been a while since I referenced those articles).
Edit: Correction: FF101 does have a couple of articles on fly lines, but no illustrations like in the linked website. I still think that I saw similar information, including similar illustrations in one or more of the articles in the archives, here on FAOL.
