HEY JOHNNY!
The No Mercy Beat'n will handle oil better than the Anger.
The Anger however is a ball that since I've thrown it has become the 'all around ball' in my arsenal. I can use it on just about any condition except the extreme 'slick' and extreme dry.
I agree with Roger on his assessment. The Beat'n was designed to go longer and react stronger on the back than its predecessor (the No Mercy) and the Anger gives you an archy type reaction. Hope this helps! God Bless You and have a great week!
