the BPPearl is a skiddy ball with the factory cover on it, depending on your speed and hand revs it could be a skid snap ball for you.. I have good speed and more then average hand revs and this ball is clean and "strong" off the spot but not hockey stick snappy or arcy either, just "strong".. the s75 is a great ball no matter how it is drilled, but as for your 2nd question I feel the s75 will check up sooner being more of a solid and the cover being stronger then the BPPearl.. the s75 is a very strong mid lane reading ball with also a strong continuous arcing motion down lane.. slashrr69
