I love mine, completly unique reaction in my arsenal. It may be close to your beserk.  I have a outlaw and bandit...and the backend shape just isnt there.  The 2nd dimension was very fun to throw as it was a great combo of midlane traction (particle pearl) with a unique hook shape from the core. 

The prodigy used the same cover, with the centripetal core (compared to the 2nd, the prodigy produced a overall smoother reaction)

Im sure there are some 'professionals' on here LOL that may have more to say..but that is my experience of the 2d so far.

Defiant Edge, Particle Pearl, smooth rolling core, ball digs in without getting sideways.

I still have not found the perfect replacement for my second dimension, but right now the closest thing I have found so far was the disturbed, but drilled for more length, and smoother reaction.

That was what I was thinking...but anytime I make a reference like that I get corrected haha.  Im hoping for the third ball in the disturbed line....hopefully they do something cool with the cover.
