Using the Rigs:
With the rigs above, you don't just cast out into the weeds and reel in. You have to have fun with it. Pretend your Texas or Carolina rig is a bug that is exploring the weeds. Let it sink to the bottom, let it slide over logs and Lily Pads, let it pull through thick grass. Make your rig look like a living creature that is searching for food among the grasses and weeds. Let the bass think it's an unsuspecting food item. The more natural you make your rig act, the greater chance you will get a strike.
These rigs are traditionally used for Largemouth Bass but they work great for Smallmouth Bass. Smallmouth Bass like to spawn in areas where there is sand and dead rotting logs on the bottom. The decaying logs help regulate the alkalinity of the water thus helping the survival of the eggs. Smallmouth Bass will still hang around these areas when the season first opens. Smallmouth Bass will also go into the thick weeds to hide from Muskie and Pike. Generally, you want to use the Texas Rig where there are a lot of sticks and logs in the water. The Carolina Rig is best used in thick weed cover.
