I don't think we have a better option at FB currently.

Balmforth back in full training by all accounts, and Chamberlain as it stands seems good to go. So if that's the case I'd line up something like


Pryce
Briscoe
Hardaker
Rapana
Martin
Cust
Sezer
Ese'Ese
Bourouh
Knight
Chamberlain
Aydin
Asiata


Eseh
Ashworth
Watts (if fit)
Balmforth


Warrington don't have a great forward pack so I've gone with a big bench to hopefully keep rolling them through the middle. 
A bit of a change around with Aydin in the second row. Could instead put Ashworth there and Aydin to the bench. However if Ashworth plays second row I'd be tempted to start Aydin at prop and put Knight on the bench as we lost a lot of impact when Ese'Ese and Knight both came off.

In the circumstances not a bad squad ....

Would play Cust with Seizer. Going well this year and we look a better team with Cust in ...Pryce can play FB with Rapana centre or wing ....
