I email BTM the same question, here is what they replied with:
@@@@@@@@@@@@
Unfortunately, it looks like we won't be reviewing the Hustle INK. Sometimes, we don't get to test every variation of the lower-end performance balls. We really wish we could have tested the INK, though, as it looks like it's going to be pretty popular. But, it was unfortunately never submitted to us for testing.
This might change, as sometimes ball just show up much later than expected, but as of now we don't expect that we'll get to test it. I'm really sorry for the inconvenience.
Sincerely,
