Having success with a worm is usually more dependent upon where you fish it. I f you throw it next to cover like stumps, laydowns, holes in weedbeds and lilypads, you can usually catch something. There are hundreds of colors, but black, purple, pumpkinseed, and watermelon are the most popular because they are the most productive. I prefer to use them weightless, and a 1/8th ounce jighead for faster retrieves in clearer water work best for me. Texas rigging works great also, of course. There are about as many ways to fish a worm as there are different styles of worm. Try different tactics and see which ones work for you. The way I learned to use them was when they were the only lure I took with me. Then I couldn't fall back on old methods if it didn't work right away. Now I use them more than anything else. Once you use a Texas rigged worm in the worst areas you can find without getting hung up you will be more confident in fishing the areas that hold more of the big fish. Good Luck!
