The Texas rig is the first thing to learn after a knot, because it is the presentation that lets you fish where fish actually live. Wood, weed, rock, laydowns. Places that eat an exposed hook on the first cast.
What the rig is doing
A bullet weight ahead of a weedless-rigged soft plastic does two jobs at once. It gets the bait down, and it noses through cover instead of catching on it. The bait follows the weight into places you would not otherwise be able to fish.
Pegged or free-sliding
Leave the weight free and it separates from the bait on the fall, which gives you a slower, more natural drop. Peg it with a bobber stop and the whole rig moves as one unit, which is what you want when you are punching into heavy cover and need everything to arrive together.
Start unpegged. Peg it when the cover gets thick enough that the separation is costing you hook-ups.
The one detail that matters
Skin-hook the point. Buried too deep and the plastic will not collapse on the hookset, so the point never reaches the fish. Left fully exposed and you are just fishing an open hook. Just under the surface is the whole trick, and it is worth re-checking every few casts because the plastic moves.
