Goddard?

[daniel lucanus]

Hey guys,
Just a bit of help on my backline and spending my free cash. My backline is:
Carrazzo, Fisher, Hodge, Shaw, Mackie, Hunt, Lisle with Webberley and Trengove on the bench.
I have $100, 800 in the bank and I was wondering if it was worth spending it on upgrading Mackie/Shaw to Goddard? Or perhaps just upgrading to Gram or Enright leaving me with around $70, 000 in the bank?
Or is it even worth changing my backline at all?
