OK, well i got this ball drilled up Sat 12-7-02, and it was drilled 4x3, Pin 4, cg 3, with a weight hole at a 5 o'clock pos, below the thumb. Anyways i got this ball because, i needed a ball for heavy oil, and since it was a particle, ball, i would give it a try. I used it for 4 games on Sunday in a scratch tournament, and i bowl at this house in a regular league and it normally puts out a heavy amount of oil from 10-10. And i was able to play inside of 4th arrow to 15, and still have it make it to the pocket, were any other ball i have wouldnt make the turn. Well, i will say that this ball hits, a ton, left only 2 -10pin, in four games. I did, hafta take a scotch brite pad to it, by hand, cuz in outa box condition, it wasnt enough to play in the soup. But the scotch brite did the job. Anyways, i plan on leaving this ball as is, and not changing the cover stock again. I will say that when this ball finds dry, it will turn hard. I did leave two pocket splits, one a 7-10, and a 4-9. But besides that, this ball is a great heavy oil ball. Oh and this is my first ball since 97 that wasnt a STORM ball, but since it is made at the STORM FACTORY, i figured why not, lol. anyways, i give this ball a 10 outa 10 great ball ROTO GRIP
