I am trying to help a teammate with a ball replacement choice.  Lady, righthander throwing a backup ball, don't know her specs but not a big ball movement.  Currently throwing 900 Global-Inception DCT Pearl (asym).  She is hoping to get a new ball with a little more back end ball movement.  I was thinking of going to a sym core maybe with a less agressive cover.   Would like to stay in the 900 Global/Storm/RotoGrip ball groups.   Please provide any suggestions/ball choices.  Many thanks.
