Gotta revive this thread, this ball is killing in my house right now. I just picked one up tonight, my first Track ball, and wow this is a reaction I have not had before. I'll post specs in my review as I picked it up tonight without my pro shop guy being there so I couldn't get the exact specs. On medium/medium heavy super clean through the front, read the midlane perfectly, had a very strong controllable snap in the backend(if that even makes sense lol). I hit very hard and kept the pins low. On flush shots, every pin dropped almost at the same time, no love taps, no messangers, just straight low pin action. This ball reminds me of a cleaner, yet stronger Nomad Pearl, with its sharp angle but great control. Definitely a sleeper and worth a look by anyone.
