The Welsh club were narrowly beaten by Rotherham Titans in their pool opener, while the defending British & Irish Cup champions had two tries from Corey Hircock in their 26-22 win at Plymouth Albion.
For the round 2 clash at Tralee RFC (kick-off 1pm), Stringer will combine with Scott Deasy at half-back with the fit-again Luke O'Dea lining out at full-back.
Local favourite Danny Barnes is at outside centre and Hircock will be hoping to continue his try-scoring exploits on the left wing.
