Smith watched his side record an impressive 3-0 victory at Carlisle before following that up with a 3-1 win over Shrewsbury last weekend, with in-form striker Will Grigg bagging five of the six goals.
And, with no injury or suspension concerns, Smith will see now reason to change a winning formula for the trip to Wiltshire.
Defender Ben Purkiss returned to the bench against neighbours Shrewsbury following his hamstring injury, while fit-again Richard Taundry is also now back in contention after his ankle problem.
The Saddlers, eighth in League One, are seven points adrift of third-placed Swindon and just five short of the play-off places.
