you can technically use any ball on any lane condition if you want to change the surface, but from what I read the SS stands for Super Strong. The chart shows that it made for medium to heavy oil.

Everyone's definition of "heavy oil" seems to be different.  I believe the ball at factory surface of 1500 handles plenty, unless you're speed dominant, and then I'd guess that it would still handle medium volume well. 

I am neither speed or rev dominant so I tweaked mine to 4000 so I could play in my comfort area on typical house shots, and it's still smooth and easy to use.
