Either one.  Might as well go with the U-Turn Particle for some true oil.  The Shock can handle oil, but it's smooth enough to fit into the medium range of oils.

I'd heard the shock was Columbia's earliest starting ball of the last couple of years.

I personally don't use that theory for flat oil but for oil inside and dry outside then i loop.

Don't know if this ball has backend on wet backs though.

I have a friend on here that swears by the Ti Messenger friction NO matter how much oil.  Seeing early start AND backend.

I have had good success on very wet patterns pointing with an Icon 2 which I can also loop in league!  Mucho backendo!!

Uturn Particle like the Formula is suppossed to be great for wet dry!  Pretty smooth backend if you like that on heavy oil.
