Why do you offer an oiled finish as a standard finish for necks?

The standard finish for the necks is an oil finish, because most people prefer the smooth, natural feel of an oil-finished neck. But also because, with an oiled fingerboard, an oil-finished neck is more humidity stable (with a painted fingerboard, a painted neck is more humidity stable). This is because for the neck to be humidity stable, the back of the neck and the fingerboard should gain and lose moisture at an equal rate.
