I recently drilled up an Inferno for something
different in my arsenal.  The pin is over
the fingers and cg bumped 1/2 positive.
I had the factory surfaced changed to
a smooth 1200 without polish.
I've experimented with it for two straight
weeks in one league starting with 280 one
week and 290 the next.  Obviously, it matched
up!  Trouble is ...... the last two games
each week were "trouble".  Lots of carry
and reaction problems.
It just sees lane transitions differently
than my other stuff and hits like a cream
puff after the first game.
We all feel "bad" shots, but that's not
the case here.
Any input would be appreciated!

String the Strikes and Fill the Frames ..... Good Bowling

I've noticed the same things already mentioned.  It works best for me with around a 2000 finish on it--just below a shine.  To rb27, I think maybe your problems with it later in the evening might be the ball burning too early.  As Bob said, you have to know when to put it away.  For me, it works better as a go-to ball when the light load particle stuff I start with starts to burn too early.
