AoS Saurus Old Blood Weapon choices

[Tony Vainer]

Hey guys.
Im going to be running a saurus oldblood on foot to support my other saurus. Which weapon option is best for him? The suntooth maul, celestite warblade, celestite war spear, or celestite greatblade?

I personally prefer the suntooth maul or the great blade, the rend helps and the boosted damage with less rolls makes it a bit easier to buff or decide if I need to use rerolls if I have any available.
