Core is the same on these two balls, but supposedly the TT's cover is much different and at least a notch stronger than the Threat's coverstock.
I think the Track Triple Threat may be one of the few legitimate "threats" to the reign of the Inferno and the original X-Factor. However, Track being so small and their ad budget being smaller yet, I have seen no Triple Threats in my neck of the woods ... yet.
Around here if you don't have an Inferno or an X-Factor, don't expect to compete. (No, I can't believe I said that either, but I know what I am seeing.) No other ball comes close lately. I haven't seen this situation since the original freaking Danger Zone.
