Richard Hodges is taking no chances with the cup challenge of Carmarthen Athletic by packing the side with his most experienced players.
Mark Roper starts at outside half with Jason Pocock coming in at fullback.
In the pack Matthew Bolton starts at prop, Nick Kelly resumes as captain in the second row and Richard Thomas and Mike Grimes both start.
The one survivor of the last time the two sides met is Mark O'Leary who is amongst the substitutes. The game also sees the return to the side of Lee Highgate who starts after an enforced layoff.
