So from my understanding, this change will make it a better fit in between the Rush and the Silver Streak Solid? Both the Rush and the Retro Res will be 1000 grit sanded, with the Rush having 11 length and 18 backend, whereas the Retro Res will be 13 length and 18 backend. This ball will now be longer than the Rush but a similar move? It'll also be a little bit weaker overall than the Rush, but a little bit stronger overall than the Streak Solid. Correct me if I'm wrong, thanks for the info.
