The best spinning rods for catching smallmouths is light to medium spinning gear.

Spinning Rods
The spinning rod should be light enough to have the sensitivity to detect soft taps of the lure, yet stout enough to penetrate the tough mouths of the larger smallmouths. If the rod is to limber you will not be able to properly set the hook, especially on quick strikes. A rod that is to limber can also make it harder to impart the proper action to your lure. The best all around rod is a medium light to medium, fast action, 61/2 -71/2 foot graphite rod with a relatively stiff butt section and a more sensitive tip.

Spinning Reels
A spinning reel will provide the needed casting range for the variety of water habitats of the smallmouth bass. A medium size reel made to hold 6-10 lb. line works best for most situations. A reel with at least 4 ball bearings will provide the smoothest and farthest casting. The ability to cast far is essential in shallow and clear water, where the smallmouth can be very easily spooked.

Line
A clear, limp, easy casting line with as little memory as possible is best. The most versatile line is an 6-10 lb. line. This will provide the best combination of feel and strength. When smallmouth bass fishing in rivers you will want to opt on the slightly heavier end of the spectrum due to the abrasion from rocks. There are 4 diffreent types of line to choose from; monofilament, braid, flourocarbon and hybrid lines. Mono line is the least expensive but needs replacing the soonest. Braided line will allow you to reduce the diameter of the line while maintaining castability and strength as well as reducing line twist. A hybrid line that blends flourocarbon and mono to give you the benefits of both is also a good choice.
