My review of the BPA by Lane Masters is quite simple. The pearl cover does everything it's intended to do. The ball has a very smooth roll through the fronts and mid lane, then it gets unleashed on the backend. As for any ball, surface change can be made for preference and depending on condition your on.  This is a very versatile ball as it can be used by rev or speed dominant players, pin up or pin down IMO. Very easily can be your benchmark ball.
Cover- XRT 821, Core - Dynasty, Finish- 2000 grit sanded, RG- 2.557, Diff- 0.059.
I throw righty at about 15.5 mph, rev rate is around 400 to 415. I have had success playing straight up 7 to 10 board or moving in and playing the middle of the lane. I bowl on synthetic lanes with 41 foot house shot, kegel flex oil machine doing the dirty work.
