happy with the team, looking to do an upgrade in the next couple of weeks baring LTI and hopefull another in 2-3 weeks. I am just not sure who to upgrade.

Which two would you upgrade?

[Jayman]

hold 'em mate!

[Samm79]

thanks Jayman,

How long to hold them?

[woofy]

until you cant win league during finals... its good to have 4-5 trades for rounds 19-22. you have 3 so save them for injurys or until your playing an opponent you cant beat

[roo boys!]

Make sure you don't hold them for too long though, with that cash in the Bank...

[Samm79]

yeah, it is tricky. I am sitting on top of the table and should be there at the end of the season.

I really want to finish as high as I can on the overall and with this being my first season I have no experience to draw upon.

Assuming no injuries can I make one upgrade at about the round 19-20 mark or should I just hold them until Chappy is rested or someone is injured?
