The major difference between the SJ and SJP is the coverstock. the SJP uses a polished reactive pearl, where the SJ uses a dull solid particle. Sanding the SJP would make it closer to the reaction shape of the SJ, but the SJ would still probably hook a little earlier and handle a little more oil. Can't go wrong with either ball though. awsome core in these things!
