The Wizard is an earlier rolling reactive. I play about the same line with it as my Sidewinder. It excels on tough shots.
The Mammoth needs LOTS of oil. Higher ball speeds can get away with throwing it more often, but my Sidewinder is a more versatile ball for my game, especially at 2000 abralon instead of the polished finish.
The Rampage can be used on house shots just about anywhere. A bit stronger at the back ends than the others due to the coverstock.
