The Reloaded is NOT polished. It is a pearl particle that comes 1000 grit matte (dull, not shiny, but not truly sanded either).
The Reloaded is more likely for medium-heavy to heavy, with more backend than the Addiction. The Addiction is generally considered to be a true heavy oil ball. I believe you'd have to polish it or drill it VERY mild to get it to perform on medium oil. If your speed is high, I'd lean toward the Addiction.
"storm claims that the reloaded hooks well in oil and finishes hard in the backend."
There is not one manufacturer that has not claimed that performance in every ball they have made in the last 20 years!
If you must have back end, however, I'd go with the Reloaded. It all depends on exactly how heavy the oil is and where your "18 mph" was measured.
