Best mid?

[grant17]

So I'm going to downgrade j riewoldt ( yeah I know it's about time) to Callinan so I can upgrade bewick to a premium with 410k to spend.

I already have Pendles swan ablett Boyd hodge and currently fyfe in my mids ( will move fyfe into forwards to make room
). I have 5 trades remaining and am sitting just outside the 8 in a difficult league and am up against dr dream team this week and am  in need of a win.

Was thinking of bringing in s thompson to give me a differential but am worried about his form against the saints (-10 on his overall average).
  I also have shaw to offload, probably to Fischer when he bottoms out but lower is good cover atm.  This would leave me with 2 trades and about 20k for finals. Might be cutting it a bit fine but there is no point leaving
trades for finals if I don't make finals( in te top four in my other league though)

Thoughts? Any other better options?
Cheers
