someone may have asked this questions before, but I am trying to bring my 04 Z back to its "touring" specs starting with replacing my after market springs.

I have an option of going back to the original OEM non-revised springs or getting a set of the revised ones (I think Nissan started using them on 04.5+ cars).

Any recomendations on which I should use?
My main objective is to get the "softest" ride possible out of my Z.
