I took mine to 2000 and it reacts much better. 4000 was way, way to close to my regular gravity with out the forgiveness. 4000 had too much over under. The pro shop owner did the same also and we both have had greater success.
It doesn't lose the hitting power, but now rolls more consistent. It is still angular, but with it getting up a bit earlier it is touch smoother.
I can't compare it to the Dimension b/c not a lot of people in my area throw it and the few that did, didn't have great things to say about it.
