Who to trade Heath Shaw for??

[tank33]

I need to trade Heath Shaw and Porplyzia either both this week or at least one of them. I am in an elimination final and have 3 trades left and 270,000 in the bank. What would you do? Options are trade both for Pavlich and Basset or Bock. Or go for say J Bowden/Gilbee and take a less expensive forward and a punt on B.Hall. Depends if you think forwards or backman are better to spend the money on. Last option is to do nothing and go with Proud and Valentini but not in an elimination final I think.
Team is..
B Newman Roughhead Gram Birchall Fletcher McCleod Proud (H Shaw Myers)
C G Ablett Bartel Delsanto Goodwin Pendlebury Stevens (Dalziell Polkinghorne)
R Cox Simmonds (Kreuzer Hampson)
F Franklin J Brown B Johnson R Murphy Bradshaw T Cloke Valentini (Porplyzia J Morton)

Any thoughts would be much appreciated.

The other thing is that my opponent has Riewoldt and Pavlich but not B Hall, J Bowden or Gilbee. So do I block them with one of those two guns forwards or go different to get more differences?
