yes, I understand a larger treble has been in the process of being tested this GT season in Japan. If all goes to plan, we should see these rollout before too long. Of course, it might take a while before we even see it. I'm not sure it is going to be a ST-76 though. I suspect this hook may have a different configuration.
Recorders are outrageously priced, as are the big GT Decoys.
