32 Monk here, using:

Main hand: Pristine Xennskin Handwraps: 39.45 DPS, 53 HP
Off-hand: Claws of Bloodletting - 33.33 DPS, 18 DEX, 34 HP, 1% melee damage.
For skillups: Knuckles of the Vine: 25.85 DPS, 9 DEX

2-Hander (mainly for AE damage near the Wardship):

My Martial Sword and Martial Staff are crap, I just use them for skillups.
