The Black Pearl was the first of three balls in this series. The Black Pearl is a true two-piece ball with a particle pearl coverstock (carbon particles) whereas the Black Pearl Reactive is a pearl reactive and the Black Diamond features a solid particle coverstock (diamond particles). Each of these use a high differential radius of gyration core. The rest of the ball is all coverstock (no filler or wrap). Like other Lane Masters/Legends two-piece balls, their hitting power is second to none. One of the two-piece design traits is a high coefficient of restitution which is responsible, in large part, for the trademark LM/L "crack" when one of these balls hits the times. All of these, the BP, BPR and BD have excellent hitting power in the hole and shred racks on low pocket hits. Like the others in this series, the BP is closer to an angular reaction than an arc reaction. The BP hooks up late in the midlane and makes a well-defined move when it sees dry on the back or side of the pattern. The BP works well on medium to medium-heavy conditions out of the box. Gold pad (2500-grit FEPA) or Gray pad (1500-grit FEPA, 800-grit ANSI/CAMI) work well to extend the BP to heavier conditions. I wouldn't use it on light, light mediums or short patterns. Leave those to the BPR, Buzz or Hornet. The core in this ball has flare monster potential. With your rev rate, I wouldn't drill it stacked leverage on anything close to it. Pin over ring finger with CG kicked a little right is good for a well-defined skid/hook reaction. Pin under ring finger, with CG kicked right is also a winner with a little bit less defined break point more of a strong arc reaction. 5 x 4 1/2 or 4 3/4 x 4 1/2, and 5 1/2 x 5 all work well with the BP. The BP doesn't absorb much conditioner and doesn't show much wear. The coverstock material is smooth enough to use without an insert. You'll notice when you sand or scuff pad the ball surface that it is harder to adjust that many of its competitors.
I like the BP, BPR and BD a lot. Along with the Buzz Attack, these balls are not your typical LM/L controlled reaction balls. I'm glad Lane Masters broadened their product line with these.
