There is no crankbait that is more resistant to hanging up on wood than the MudBug by Arbogast. Additionally those crankbaits made of wood are generally more bouyant making them better choices than those made of plastic that do not come through the cover as well. You have heard anglers talk about confidence lures. Confidence lures are great as long as you do not try to force feed the bass a lure that he does not want on a given day. Develope confidence in several different lures and different techniques.
Versatility is very important in bass fishing.
Do not try to master every technique that you read about, but experiment with each until you develope types of fishing that you are comfortable with and enjoy employing. Try them, give them a fair chance, but if they are not working do not assume that the fish are not in the area you are fishing or that they are not biting. Many times a slight adjustment in presentation or lure selection is all that is needed to turn a fishless day into a great fishing day. Understand that every day is different and the fish just do not actively feed every day. Learn that when all the things that you have tried are just not working, that it might be the time to select the technique in which you have the most confidence and just keep a hook wet.
