I had bad results with my Dimension polished. I put the same surface on my dimension that I always do with my gravity shift. What I wanted was a gravity with a bit more midlane roll just to see what it would be like. Well what I got was a dart. My Gravity reacted the same as always but my Dimension would never pick up a roll. I have no idea why, it seemed very odd to me. I did the exact same thing that I always do to my gravity but it just didn't work.
I'm sure my results are more outside the norm just giving my experiences.
