Is high-sulphur nickel strike worth it?


We are considering adding a high-sulphur nickel strike to our duplex nickel process. Based on information I have gathered, the strike is more cathodic to the semi and the bright and would be sacrificial. The millivolt potential difference between the bright and strike is supposed to be 15-30 millivolts. We also have a "dull" nickel in our plating line that currently performs the same way electrochemically.(approx. 30 millivolts cathodic to the bright).

The question I have is:

Is there an additional advantage of the strike that would increase corrosion resistance over the dull nickel?
Is the strike's only benefit it's electrochemical potential difference?
Is there anyone out there who has done any experimentation in this area?
