All of stack, rioli, castagna and aarts are in poor form. Honestly wouldn’t know who to drop out of the lot of them. Probably george since he’s been poorest for longest.
Soldo was poor but atleast got involved whereas Chol was mostly anonymous. I wouldn’t play nank as no.1 ruck against nicnat in his first game back. Think you need to give him a couple as second ruck before you then look at the benefits between chol v soldo.
