It will go longer because some mica (dusted minerals, sometimes other compounds) is added to the coverstock base. The material is a bit harder. I amsure, when you have a Nemesis and a Rampage, one pair polished and one pair dulled, and tested on the same condistions, the pearl ball will react a bit less and more skid/snap than the solid one, which grabs the lane better.
Ever wondered why mostly any light oil ball is a pearl and why heavy oil reactives are almost completely solid reactive? It is because of the general coverstock characteristics. Therefore, the Rampage is better suited for medium-dry conditions, while the Nemesis is better suited for medium-oily shots. The make up a very nice combo, though.
You will rarely find a sanded pearl ball for heavy oil. I guess the TPC Player is one of the rare examples?
