37 monk

[MogManX44]

My monk is currently 37 and i've been using Wu's Quivering staff (and occasionally 2x wu's trance stick) as my weapons.

some other gear info - i have schw for haste, robe of living fungus, and hp/ac rings.
also wearing almost a full set of wu's armor.

I'm looking to get the most impactful upgrade i can for ~3.5k (maximum)

I'm thinking this means upgrading my weapon.

For a mostly solo, relatively untwinked monk what weapon upgrade would be most efficient, ive been thinking Peacebringer, but would love some input on that vs 2 1 handers or even other 2hb weapons i can afford.
