ROC-DX

Innova invented midranges back in January 1987 and this is one of the classics.

Everything that came, came later.

It would be very difficult to say anything new about this disc, really. So we're just going to agree with Philo Brathwaite in this video.

Having multiple Rocs and rotating them based on stability is the most old school and a thing you should probably do.
