Either the Primal Rage would be a good step down from the Raptor Talon as long as you have the ability to move in substantially. It is still a strong ball and it benefits those with the ability to move in and bang it off the dry after there has been a spot developed.
If you still want to stay in the "tweener" region after the lanes start to break down, perhaps the Primal Scream would give you a little more versatility in the line you play. Just depends on how much the shot changes after you move away from your Raptor Talon.
Either way, I don't think you can go wrong.
