Please help! final roll of the dice

[kma07]

Hi guys

as it stands against my opponent:
im up by 305


Simpson 60...............Burgoyne
Bews 36...............Duffield
Hanley.....................Suckling
Enright 105.............Sidebottom (C)
Libba   ......................Priddis
Beams (C)..............Beams
Ward   .....................Ambrose
Goddard.................Mitchell
Mumford................Jacobs
Parker 104..........Dahlhaus



I think I might be in abit of trouble..
I have 2 trades and was thinking of either:

Libba to Rockliff in + Pav to  Duffy
or

Mumford to Jacobs
Libba to Mitchell

to cancel them two out?

What do you guys think is the better option?
