The Raw Hammer Pain is pretty dam strong.  It comes 2000 grit abralon OOB.  I dulled one of my PAINS to 500 grit abralon and it was a beast and needed a good amount of oil.

I don't know how it compares to the ONE series but it's a very good bowling ball.  Right now I have 2 PAINS and it's my favorite bowling ball.

The PAIN does take a on a shine but the maintenance is normal.  Very durable coverstock.

One of the best bowling balls for tough lane conditions.

I would not say it acts like the One, at least as far as I can tell.  I have a Pain, and it's one of my favorite balls.  It is strong, but very smooth and easy to read and control.  I would classify the One as being a lot more in the backend, while the Pain has a great midlane read and a good backend move.

Mr. Lebowski, this is Bill Salnicker with the Southern Cal Bowling League, and I just got a, an informal report, that a member of your team, uh, Walter Sobchak, drew a firearm during league play. If this is true of course, it contravenes a number of the league's by-laws, and article 27 of the league...

BOB:  Did you see the way she was lookin' at me?
DOUG:  Yeah, because she thought you were some kind of freak!

Everything being made right now needs to be cleaned and have oil removed often to offer the best performance.  I think the Pain is a great ball and could stand a little less maintainance than the BIG ONE, but honestly the One is not that bad to maintain.  Its really no big deal to take care of a cover.  Use a microfiber towel to wipe the ball off before each shot and spay it down with a cleaner when you get done.  Then after about 50 games throw it in a bucket of hot water/ rejuvinator.
