I'd have Laurie Weeks as the frontrunner.
You could also potentially have Slipper as the third choice THP if there was an injury drama. Sio could start at LHP or you could start Slipper, sub him off early then bring him back late when the THP gets injured or however that trick works.
I wouldn't write off Benn Robinson as the 5th RWC prop. His experience is a positive and if he has a strong season he'll be there or there abouts. There'll be some sentimentality as well in finally getting him to a RWC.
Tetera Faulkner's chances could be damaged by how badly the Force's scrum is going this year.
