A teammate of mine has one and he really likes it.  It's not a super-strong asymmetric like today's quick-spinning, big z-diff cores, but it's a medium-strength asym.  The coverstock was Powerplus, which is practically Superflex.

Today it's a medium to medium-heavy oil ball.  His is drilled with the MB kicked towards the VAL and it does just what you expect: lots of midlane with a hard arc on the back.
