A medium rod is perfect for fishing with this kind of hookset, as it has a reasonable bend that ensures the line tightens into a fish's mouth without blowing it out from too much force. A medium-heavy can be easily pulled too hard as it does not bend to forgive a hookset that is too strong. That means you've lost a fish in your basket.  Yes, a medium-heavy rod is better than a medium. It allows you to fish smaller jigs, spinnerbaits, top water lures, crankbaits, vibrating jigs, and much more without sacrificing any performance.
