Texas rig without a faceted glass bead reduces strikes, in my opinion. The sound factor alone should be a good reason to add a glass bead, the bead also protects the knot and moves the hook back into the basses mouth so they don't bite the weight as easy. Bead colors should match the weight color. I'm not trying to push Top Brass, they make the best available glass beads, no sharp edges and I like there brass weights for Texas rigging. Tungsten are good for weights over 1/4 oz to keep the size down, however expensive and I tend to use 3/16 oz for Texas rigged worm most of the time.
