Did you try a PSWF Void Strike Henshin? Effective in mid epics so after an ER respec.
Monks are best as shintaos in heroics no matter what changes come due to the diversity of mob types and the simplicity of wraps—rust monsters, oozes, slimes, skellies—and the faster attack speed of wraps. Maybe use staves in epics once the better crit profiles can be used which for pure monks anyway will not happen until level 12+ with IC: bludgeon.
It is a similar issue with assassins—you are not an assassin until level 12 and the weapons of choice are lousy until knife spec. So an assassin can use the low hanging TA staff speed boost and use staves until 12. Henshin lacks this early boost but can use wraps.
