Well, then, how about this?
Superior Finesse
Prerequresites: Dex 13+, Int 13+, Combat Expertise, Weapon Finesse, Weapon Focus (any applicable for Weapon Finesse)
Effect: Pick one weapon for which you posses the Weapon Focus feat and for which the Weapon Finesse feat applies. You may add your Dex bonus to damage instead of your Str when using this weapon.
