The Game Breaker 3 Pearl is much stronger versus the GB2 Gold but the motion is a complete apples to oranges by comparison. This was a little bit too much reaction for me and the line I was wanting to play. This ball will work great for the soft stroker type bowlers who want plenty of length and angular motion down lane. It works wonders on medium oil volume conditions.
This ball is extremely clean thru front of lane and with a more down lane motion then GB3. Doesn't give you the major over reaction off the dry. If you are a lower speed player or bowl some where with a little drier condition. This ball is a must have in your bag.
