The Dimension is very strong. It really is as advertised!!! It rolls through the front like the Special Agent, but reads the mid lane a little stronger, and still has a ton of continuation. I have been on Storm staff for a couple of years now, and used all Storm for a few years before that, so I have not thrown other companies bowling balls for awhile, but I can say from drilling thousands of bowling balls over the past six years, that this ball has the perfect match of midlane, and backend recovery.
There are alot of bowling balls that are strong in the midlane. And there alot of balls that are strong in the backend. But the Dimension really does both. I drilled mine over label, pin under ring finger, on a shorter pin ball, no balance hole (a very mild layout), and was still able to leave six pins, and eight pins, as well as a fast eight playing fifth arrow on the Scorpion pattern. This ball is designed to give you continuation once moving inside on fresher oil, where the Special Agent struggled to get sevens and tens out.
As far as the Attitude Shift goes, It is a stronger piece than the Extreme. You would have to compare the Attitude today, to the Extreme, a few years ago, when it first came out. After looking at your arsenal, a Rapid fire just might do the trick for you. I would use a strong drilling (6 3/4" from pin through CG mark) halfway between your VAL and initial track ring, with pin somewhere to the left or slightly above your ring finger. this will give you skid from the pin placement, and flip from the drilling (strong).
But as I always say, talk with your local certified pro shop operator who knows your game, as it is hard to give layout advise without seeing you bowl, or knowing your game.
