Dave,
Here's the response I received.

Thank you for contacting Predator Group, and it is good to hear from you again.
Unfortunately, the BK Hybrid Break tip is not yet available as a single-purchase item, through Predator.
Predator began the process of approving repair centers a year ago, which would make these tips available through these centers, however, the process has been delayed. Customer Service is not certain when the process of reviewing applications and approving repair centers, will resume.
Please let us know if you have any further questions.

Seems they are trying to make it happen, they just aren't there yet
