DEF help please (POLL)

[benno123]

With a solid number of DEF rookies named I'm thinking of maybe shuffling my DEF set up...

Currently:
Mitchell, Hurn, Swallow, Suckling, McDonald, Langford (Langdon, Georgiou)

Thinking of changing to:
Mitchell, Hanley, Simpson, McDonald, Langford, Clurey, (Langdon, Georgiou)

If I change will also allow me to upgrade my F6 from a $117K rookie to Rohan, which given the lack of forward rookies, I think is needed. Gives my defence 3 certain keepers instead of 1 certain and 2-3 possible. Negative is I need to get 3 rookies on field each week Will look to upgrade this line ASAP when my team generates some cash. Looks very risky starting 3 rookies on field, but the rest of my squad is fairly risk free IMO and pretty much locked in, so taking a risk here may be worth it.

Advice would be great or just a quick vote above, thanks :)
