Best weapon for maul Werebear?

I’ve been playing my bear and I’m trying to decide what end game weapon is best for him. Research tells me these are the four best options:

Breath of the Dying (Great Poleaxe) - Expensive but can probably trade for the Zod
3 Socket Tomb Reaver - Add IAS in sockets but level 84 (not sure if I’ll make it there)
Beast (not sure what to put it in) - Expensive but I have the runes for it. Also gives Fanaticism aura. Low damage though?
IK Maul - Need to equip other IK pieces for most benefit - IAS in sockets?

It looks like that for bears, only IAS on the weapon helps attack speed. I assume auras (ie Fanaticism) do as well (maybe put Faith on an Act 1 merc)?

ik maul would be the budget option here that works great, if you have other ik pieces. add a Gface and you are set to farm bosses over & over.

but that wont be the end game, i guess endgame would be the high roll eth BOTD or high roll eth TombReav

Beast in a Champion Axe, if you are maxing Grizzly (and hire a might merc). One bear does less damage than two😀.
