I just received a Nedz in trade from Ed and I am also very impressed! I haven't been able to use it much, but after the weekend I'll post my experience with it. For black and grey, I can see how the Nedz short stroke would rock, it's highly customizable. With a lot of machines, you have to adjust to the hit. This you can adjust the machine to your liking and that's what gives it an edge in my opinion
