i threw the storm charge pearl during the end of last years season gaining about 15 pins on my average.  Prior to that i was throwing the original x factor.  I liked the charge pearl because of how much it rev'd up in the midlane and then it came back strong at the end when i didnt think it was going to.  i have been out of bowling for about 6 months and am looking to get a new ball.  i have been looking at the x factor ace and the depth charge.  does anybody have any reccomendations.  i am a righty with  medium revs and medium speed.  i usually drill with the pin over the right ring finger and bowl on synthetic and wood both with medium oil
