A prop rotation of Aloiai, Sipley, Paseka and Jake would be my preference but with Jake at 13 I would add Marty.
I had high hope for Bullemor at 13 but perhaps he is a work in progress. I can't bring myself to view Bullemor as a prop. Second row is pretty crowded sure but would prefer him, Ola, Schuster and Davey rotation.
Long story short, if we must play Jake at 13 then we need one more prop. Aloiai, Paseka, Marty and Keppie is simply one shy of enough.
Tuitavake? Sykes? De Luis? Fifita? Listed on the Sea Eagles site but I know not much about these guys ...
