I prefer a mix of those options:
Week 1:
Rioli to BJ
Week 2:
Nothing
Week 3:
Ebert to Bartel/Corey
Save you 40k, and I think the Geelong 3 will score roughly the same and Jimmy has every chance of beating Gaz for the rest of the year. I think Palmer is find to keep, but if you don't then use the 40k to upgrade him.
