This is a easy one for a change. The Robo Rule over the Animal. I still use my Animal every week and have tried to replace it by have not had a lot of luck.
For me the Animal is more of a medium oil ball, but that is just me.          If you can find a GP-2 that would be a great ball for heavy to the flood. For tournaments this is what I still use, when I know the lanes will have a lot of oil. Hope this helps you out some. I know a lot of Trackers will chime in on this topic.

Eather one will work great for what you want, yet you will have to sand the cover down somewhat so it can handle the flood with the best of perfromance.

Dunno for sure, but I would vote Animal.  However, your Mean Machine should do the trick, just move a little bit.
