TO me the original Legend was a nice piece, smooth with a nice mid-lane. (Both balls drilled the same)Dark Legend takes that to the next level, great mid-lane with more pop on the backend. I like the original, but the Dark is way better in so many ways. Hope this helps..

the new cover on the DL gives it more predictability IMO
it reads a bit sooner and like mentioned above, more backend under the right conditions

Thanks 12xsech, that's the assumption I got , I had the limited edition pearl and comparing it to the red legend pearl it was much earlier and smoother to my liking not saying it was a bad ball and probably a good ball on right condition when somethings get to angular
