Does the Sensei Monk ability "insightful strike" work with grappling?

[Ansibelle]

RAW: "At 2nd level, a sensei may use his Wisdom bonus in lieu of his Strength or Dexterity on attack rolls and combat maneuver checks with unarmed strikes or monk weapons."

Assuming an unarmed strike, does this ability work with grapple? If not, what maneuvers if any does it work with, again assuming an unarmed strike, and why are they different?

Sunder, Disarm, and Trip are the combat maneuvers used with weapons. They're different because they're actually performed with weapons. If you could somehow give a Mancatcher the monk descriptor, or find a similar weapon, then it would work as you want it to.

If it doesn't work, my guess would be that the ability would function with only disarm, trip, and sunder, since those three maneuvers can be performed with any weapon...

It should work if you're using a Dan Bong. Just note that you take a -4 to grapple if you attempt it without both hands, so using a Dan Bong gives you a net of -2 to the check. (You should also note that a single classed Sensei isn't proficient with the Dan Bong by default.)

Unless you have grabbing style as well, or if you use the common sense house rule that using a dan bong does not count as having only one hand available for the grapple.
