xyun, good to have a newcomer to ball reviews who wants to improve his game!!
the silver diamond will get pretty far down the lane, then make a sharp turn toward the pocket. personally, i wouldn't consider this a versatile ball. the cranberry may be more versatile simply because of the coverstock. the weight block is more aggressive, however.
if you can still get a blueberry, that would be my humble suggestion.
go to the lane #1 website:
www.lane1bowling.com look at each of the balls, which has an example of how each ball rolls. pick the reaction you want, find a good driller, and bust those pins wide open!!
