Monk Weapon Comparison Help Please

[DinoTriz]

Hey guys, I'm a level 11 Monk with a tough decision on what weapons to use (although its a nice problem because awesome people have given me these weapons)

Should I use my "Wu's Quivering Staff" (2H Blunt/ 23 DMG - 28 Delay - 9.0 Weight)

OR

Double "Cane of the Tranquil" (1H Blunt/ 11 DMG - 25 Delay - 2.5 Weight each)

Dual wielding looks cooler, but how do they compare? What about after I get Double Attack at 15?

Any help would be awesome! Thanks!
