I think you will find that it "starts-up" earlier, and is a little stronger overall, with just a little less "pop" on the back-end, at least that is what mine did at 2000ab. I now keep mine at a base sanding with green scotchbrite and the Secret Sauce applied with medium pressure(shiny but not a marble, and still able to see the base sanding lines a little). It now gets the length, is still very smooth, and got its little "pop" on the backend back, and is just a little stronger overall, at least this is what it did for me, hope this helps.
