Go to [url=http://www.troutrods.com:cf9c5]www.troutrods.com[/url:cf9c5] (Tom Morgan's site). You may not agree with all he has to say(especially the prices of his rods), but it is some good information on Bamboo, graphite, rod actions and fly fishing in general. Some of it is a bit long-winded, but don't forget to read the "articles" portion of the site.
