I still say one handers and two handers have very different purposes for a monk, or any melee... Your one handers are for fast hits that open your finishers, and your two hander is for burning the finishers. You can either add two /wear commands to all your base hotbar abilities for your wraps and have a /wear button for your 2 hander, or as I do, keep a separate set of keys with your /wear commands to the side to swap between base hits and finishers.
As Hag said, the best set of 1 handers we can get is the flawless cavalier's jagged wraps of striking. (Though the rules are different if you're Harmo ofc). With these, you'll be opening finishing chains (nearly) every hit. Your Graystone staff will then give you some very nice big hits from the finishers

Oh and as a crafter, I would never never never put a devastation crystal on a jagged wrap... You halve the values of both crit chance and melee damage rating you would get if you had used the jagged strapping or crystal of devastation alone on the wrap. Striking is well worth the investment!
