I would be quite happy to see Lui in the halves if it means one of Sutcliffe or Myler is dropped.
As for Ferres he too should be moved out on DR with immediate effect.
He offers absolutely nothing just like our two half backs.
Singleton too should be on borrowed time and is perhaps fortunate we have little competition for props.
I would go with the following:
Walker
T.Briscoe another who is just about average at best/L.Briscoe.
Newman
Hurrell
Handley/Golding
Lui
Mclleland
Ava
Lunt
Singleton
Watkins
Smith
Merrin
Subs:
Dwyer
Oledzki
Cuthbertson
Donaldson
