Well, the "plain" Energy is actually the pearl for lighter oil, say medium-light oil. The Energy is a solid/pearl combo which comes 800 grit dull and is intended for medium to medium-heavy oil patterns, depending on your hand, ball speed and drlling.
However if you MUST force this ball to play light oil patterns, and if you have any hand at all (assuming your "medium revs" is a true medium revs), i'd start with probably a 5" to 5.5" pin to pap distance AND polish to about a 1500 grit with Storm's Xtra Shine polish (very good stuff).
both the energy and the high energy covers are easy to modify, up and down.
good luck.
