ok so your oil ball is your revenge. The Nightmare OOB is going to be similar but still more angular downlane. The Brutal OOB will definitely give you more pop at the breakpoint than the Revenge. If you get the Nightmare, you may have to dull it a bit or it might be a little too similar to the Revenge. (within a few boards) The Brutal OOB is definitely going to fit above your Revenge and a slight change of surface, say a hit with a 4000 pad will make this ball a monster for you. I love the rest of your stuff the way it is. Terror is one of my faves and the Marauder line is benchmark heaven. I really think after seeing your stuff that the Brutal is the way to go.
