Not a Utah ball, as it was produced in early 2014 and discontinued before the fall releases. Pretty good ball though, I still use mine and its my go to ball when I want a good strong finish and a predictable motion. I would put it as a drop down/compliment to the Moxie. When the Moxie starts to pick up too early, the Darkness is a good ball that won't read too early, but still have a good move on the backend. I am not able to compare it to the Radar Lock or Alert. Weren't those particle covers? If so, those are going to give a different reaction from the Darkness. I think if you have the opportunity to pick up a Darkness, do it. Pin down or up, I think you'll like it and be able to use it on many conditions.
