I recently picked up a 2nd Epic for my bag.  It has a slightly different layout and cover prep.  I use both of them frequently.  This is the first time I have ever bought another of the same ball.  The Epic is just that good for my game.  What else is so good for you that you carry more than 1?  I expect to see the Black Widow many times on this list.

Had two Ebonite Reactive 8 Balls, but one cracked in half last year.

Two original Apex's.....they are since long gone and rehomed.  

Two Big Ones, drilled differently at different surface preps.
