I have to disagree. There is nothing smooth about the SS Ogre unless you drill it pin at or very near the axis. The SS was not designed for smooth transition and backend. It was designed to be the longest down the lane and most "snap" on the backend of all the Ogres, since it is the replacement for the Mean Green.
Another thing, is that a ball that tends to rev up faster will tend to have a smoother transition and more controllable backend. There are some circumstances where you could take a high flaring core and drill it with a low flare drilling in hopes to save some energy for the backend reaction. A ball that rolls sooner has to release some energy before it gets to the backend. Higher RG balls do not roll as fast unless you drill it leverage. Higher RG balls will save energy longer which makes the angularity of the backend more pronounced.
EX: A ball with an RG of say 2.55 with a diff .035 is going to be longer and more violent than a ball with an RG of 2.48 with a diff .055.
Thus, a ball with lower rg and higher diff numbers tend to roll earlier and have a smoother transition off the dry than a ball with higher rg and lower diff numbers.
If it was the opposite, then my Frankie May Gryphon should have more angularity on the backend than my SS Ogre. They are drilled identical with similar surface preps and my SS by far is longer and more off the spot.
As far as comparing those two balls, the SS should be cleaner through the heads with an angular backend reaction. The AMB Centaur is going to handle a little more oil. It will rev up faster in the midlane but the backend should be strong, but smoother and continuous. I have used both balls and that is what I get from the AMB Centaur Pearl and the SS Ogre.
Hope this helps.
