Zorko or Rockliff?

[Sh*tatdt]

In a little dilema after watching the NAB cup grand final last weekend, Zorko and karnezis really stood out but i have had Rockliff in my team all pre-season and he seemed like a lock! my problem is i dont want 3 brisbane players in my forward line so what are your thoughts?

Rockliff

PLEASE HELP!

I've got both Zorko and Rockliff, and Karnezis on top of them! I don't see a problem in having all of them tbh... But imo Rockliff is a must-have, and Zorko is just behind him. :)
