I'm with you on this. If the ball is designed for slower speeds, or the "rev-challenged" then just say so. Why risk alienating your customers by stating the ball is for "seniors" or "women"?
Jewel might be a great ball for many male bowlers, but how many are going to want to use a ball that the company says was designed especially for women?
And really, isn't it just a pearl, and possibly stronger version (according to coverstock rating) of the Lunatic?
