Forward upgrade or hold? Would love some advice!

[MsHighkick]

Am sitting top spot in my league so my little voice is saying hold this week, but I'm having trouble resisting the urge to upgrade a forward. Here's what I got:

S. Johnson, Fyfe, Harvey, Petrie, Fyfe, Franklin, N. Riewoldt, Mzungu (Sylvia, T. Lynch, Callinan) with Prestia also.... $57,000 in bank

Did want to play Petrie in the Ruck (Cox, Smith) but with Sylvia out he's playing forward this week.

I had planned to get rid of either Harvey or Sylvia but was leaning towards Harvey because of North having the bye. I was thinking of upgrading to Goodes. I'm pretty happy with my backs and mids so my last few moves will probably be upgrading forwards/keeping a trade or two for injury.

My questions: Do I need Goodes? (Other top teams in my league have him) or is there another option?
                    It looks like this is the week to get Goodes (price wise) or should I hold tight with my 4 trades knowing I'm safe on top?

Appreciate some advice - Thanks!

I'd hold trades for finals
