OK, George, the Strike Machine is listed as Nanotread Reactive on ABS, and Nano-Thread Reactive on the Track site and I'm not sure if I know my "treads" from my "threads" lol, but Fang is type of particle and Track would not have it in the descrption unless there were particles in the coverstock and I cannot see a pearl reactive, even with the robo core, being listed as a "heavy" oil ball and have a hook rating of 52 on Track's hook chart. If the Mean Machine is a "nanotread" pearl reactive with a hook rating of 52, (the Robo is 43) and is a heavy oil "control" ball, well... I'm sorry, but I just don't think that's possible. Right??
