I got my first fly rod last summer. Before getting one, a friend gave me a lesson on his slow action 5-wt rod. I didn't like that the rod seemed to jiggle and bounce. I don't know if that was the specific rod I was using (cheap or old and poorly maintained) or if that is normal for slow action rods. That said, I tried casting a few slower action bamboo rods at the DCFF expo a few weeks ago that didn't have that jiggly feel. I got a 6-wt fast action rod that's felt great catching dozens of panfish so far.
