The Rampage is meant to, and does, handle more oil than the Punisher. Both balls utilize the same weightblock. The Rampage sports a pearl powerkoil 18 cover, while the Punisher uses a form of the N`Control coverstock. If any of you have ever rolled a Black Ice Danger Zone (PK 18 Pearl), and also rolled a Purple Pearl Command Zone (N`Control), then you would know the differences in these two covers. The N`Control on the Punisher is meant to react less in the oil while providing a strong but controllable reaction off the dry. The PK18 is what it always has been, stronger in the oil and strong off the dry. By that logic (and because i've thrown both balls, drilled the same), I would venture to say that the Rampage is 4-6 boards stronger than the Punisher, with that number varying slightly depending on your release strength and ball roll. Hope this helps.
