Lower_level,
Just a little more information to help you make a better decision:
The S75 is already a big hooking, very strong mass bais ball. You/your driller would also have needed your accurate PAP to drill this one correctly.
For the average bowler, there's not going to be a day and night difference between the S75 and the Rogue Cell, BOTH drilled correctly.
One other fairly important fact about strong Mass Bias balls, the bowler needs a good deal of consistency in their release and ball speed to make these work well. That is, in part, why your specific release specifications (PAP, tilt, roation, ball speed) are all essential when laying out these balls.
Good luck, no matter what you decide.
