Your all mental.... Olbison is good dont get me wrong but after his preseason id stick Walker in the second row and have Olbison off the bench... we cant afford to leave Chev out the starting lineup

Donaldson and O'Brien to miss out for me. They will probably play for Dewsbury.

Walker will play in the front row

Good selection IMO. He's a tackling stopper in defence and adds pace to attacks.
Not the conventional prop by today's standard but it might be an inkling of how FC will use his relatively lightweight pack this year.

Suspect Langley will do the propping role with walker covering at 13 when Langley is at prop or off the field. Guess we'll find out tomorrow.

As you say we find out soon.
This lad Cummings is an astute fellow, and I think we can expect the unexpected in a game plan.
