My Ravage IV can handle a bit more oil than my Ravage. My Ravage IV is layed out with the pin 4 1/2 from my PAP over the ring finger and the MB between my thumb and VAL. My Ravage is drilled with the pin 4 inches from my PAP with the pin under the ring, MB in the same position as the IV. It makes a stronger, more continuous move through the pocket for me and is a bit more forgiving than my Ravage. I can play more inside with the IV on oiler conditions but I can still use both balls in my arsenal because the compliment each other. Both still have the OOB finish and about the same amount of games on each of them. These two are among my favorites from MORICH. You can't go wrong with either one. Both coverstocks are easily tunable.

Hope this helps.
