Tungsten Worm Weights
Tungsten weights are much denser than lead to reduce the size of your bullet weight and since tungsten is denser, the size of the weight is much smaller than a lead weight weighing the same amount. That means your Texas-rig will be more compact and more able to get through small spaces more easily. Tungsten is also much harder than lead, which gives you more feel for the bottom. If you haven't tried tungsten, you'll be impressed with the feel you'll get for where your weight is.
