VoP ANYTHING is good in that situation though. VoP comes out to be ~60% WBL, when you add everything up. If your DM is only giving you 20% WBL in treasure, automatically getting 60% WBL is a pretty dang good deal. A VoP fighter wielding a quarterstaff 2handed with Power Attack is gonna dramatically outclass and out damage a VoP monk.

Its not a function of monks, its a function of DMs and WBL.
