Weapon Finesse + Greater Whip Mastery = ?

[Peter J]

The Weapon Finesse feat allows you to use Dexterity instead of Strength with you CMB when perform a combat maneuver with a finesse weapon. In this case, a whip. The Greater Whip Mastery feat allows you to grapple with a whip. Can you apply the Weapon Finesse feat to this situation as well? In the FAQ, it said that only disarm, trip, and sunder can be used with a finesse weapon, since there are no weapons that allow you to grapple.

The FAQ wrote:

It depends on what combat maneuver you're attempting. Disarm, sunder, and trip are normally the only kinds of combat maneuvers in which you’re actually using a weapon to perform the maneuver, and therefore the weapon’s bonuses apply to the roll.

Using Dexterity should be legal.

Normally grapple is not done with a weapon, but this feat specifically allows it for whips. So yes.

And does Greater Whip Mastery allow you to use bonuses on the whip to give a bonus to your grapple check, as with other maneuvers made with the weapon?

From the SRD:

When you attempt to perform a combat maneuver, make an attack roll and add your CMB in place of your normal attack bonus. Add any bonuses you currently have on attack rolls due to spells, feats, and other effects. These bonuses must be applicable to the weapon or attack used to perform the maneuver.

Yes. If you're using the whip to make the combat maneuver check, you get all of its benefits - Masterwork, Enhancement, Weapon Focus, and your Dex mod in the case of Weapon Finesse.
