My reckless balls are my benchmarks, first out of the bag at pretty much every house I go to.  A good middle of the line ball, very smooth and easy to read.

 

My Revenge is a lot earlier and much stronger off the spot, I tend to use it on higher volume or longer patterns, especially on synthetics.

 

Overall for me the Revenge is 4-2 to 6-3 stronger than my Reckless depending on lane surface and oil pattern.
