Monk Weapon Question (Duo w/ Shaman)

[Braldar]

Hi All,

My wife and I are duoing a Monk (her) and Shammy (me) and I'm trying to figure out the best weapons for her. We are both lvl 21 and she is tanking, mainly because I can't pull agro... She has 2 Master Wu's Trance Sticks, a Cane of the Tranquil, a Wu's Quivering Staff, and a Peacebringer.

Since she's tanking for a Shammy, what weapon(s) should she be using?
