I suspect Scholz will play, as he seems to be part of a project.
I would play Cardell, and let Fifita cover 6 and 5 against a tiring [and they really tired against Sarries - after about 12 minutes] pack.
Give McHenry enough time to see if he can make the grade.
Malins may have had 4 tries handed to him on sunday, but Crossdale was the man who was under pressure and delivered.
