I bowled with the Jewel last night.  In the beginning, I felt like this ball was not for me due to my ball speed and bowling more so on oilier lanes.  I recently threw the ball and had much success.  I averaged 220 after taking off for 2 weeks. I am very glad I grabbed it out of my bag.  This is definitely my new dry lane ball! I work well for down and in bowlers, with slow ball speed. This is definitely a great ball for women!
