Tibs or Double Bronzeback ??

So I am working on a Morghoul1 list and I am trying to decide if I continue to use Tiberion or swap out for a second Bronzeback.

The current list:
Master Tormentor Morghoul (*7pts)
* Cyclops Brute (5pts)
* Bronzeback Titan (10pts)
* Tiberion (11pts)
* Titan Gladiator (8pts)
Farrow Bone Grinders (Leader and 3 Grunts) (2pts)
Gatormen Posse (Leader and 4 Grunts) (9pts)
Paingiver Beast Handlers (Leader and 3 Grunts) (2pts)
Agonizer (2pts)
Extoler Soulward (2pts)
Mortitheurge Willbreaker (2pts)
Orin Midwinter, Rogue Inquisitor (2pts)
Paingiver Task Master (2pts)

I currently use the Posse to hold a zone or deny a scenario piece while the rest of the army wrecks the board. The reason I am contemplating a swap is that Tiberion doesn't have the movement shenanigans that a Bronzeback brings to the table. Both can wreck virtually anything in the game single handedly, but the lateral moves 'trainwreck' gives me is nice and somewhat deceptive.

Thoughts?

How would you spend the extra point?

Gobbers, def 19 Morghoul with 'safeguard' animus is pretty legit. Also with this many beasts maybe a Feralgeist would make the table.

Most likely Gobbers though for the concealment.

I would keep Tibers...You already have one Bronzeback. Might as well keep the more durable late game bruiser.

I second Tibers. Reach is worth one and a half beatbacks, and he gets it for free

Thanks for the feedback. Will keep the list as is and see how it goes. Only have a handful of games with it....off to test it some more.
