The Drovers find themselves in second place behind Llanelli albeit with a game in hand after three bonus point wins so far this season. And they will be looking to return to the top of the table against the all Whites.
And their free-flowing backs will be the main source of worry for a Swansea defence who conceded 25 points at home to Cross Keys.
Sam Davies will again be the key man for the visitors as he looks to get his backs moving from fly-half. In the forwards, captain Paul John leads the side from hooker lock as Sam Kiley is rested to the bench as the quick turnaround between games sees the visitors make a number of changes. Sam Lewis comes into the back row while Chris Shelmerdine and Nick Harwood once again combine in the centre. Dangerous winger Jordan Skidmore misses out completely.
For Llandovery, the lack of a midweek game means they can name many of the same side who comfortably saw of Bridgend last time out. Kieran Murphy comes in for Luke Kendall at No. 8 while Cerith Rees, who enjoyed an influential game against the Ravens, has to settle for a place on the bench for the clash at Church Bank.
