Do I go light in the rucks? or roll the dice with only 3x stud midfielders?

General comments appreciated...

My main problem at the moment is do I go with the above structure? or downgrade D. Martin to a rookie premium and upgrade one of my bench rucks to Sandilands? can a ruck by committee of Gilles, Stephenson, Witts/Derrickx, Rowe get the job done?

[essendon2]

Sandilands + Smith
or
Giles + Martin

100+65

65+100

I'd go Martin+Giles purely because the chance of Sandi getting injured
