A good rod may not instantly make you a better angler but a poor rod will be a limiting factor for any angler. Your rod is a tool, and a good craftsman will always do better work with a good tool. A good rod will allow you to feel much more of what's going on with your lure. For instance, you'll be able to tell if you're dragging your jig through mud, sand, rock, sticks, etc., and more importantly, when you get bit, which can often be hard to detect.
