I am no expert on discs, and only recently ventured out of my Hero Air blem comfort zone....
But I just bought a handful of Hyperflite pup discs and do not like them at all. They're hard to throw (maybe with more practice I could do it?) and my dogs bit through them in one session. I couldn't imagine tugging with them.
I have one Hyperflite Jawz that feels just like the regular....I haven't used it yet.
I am going back to Hero Air 235 I think -- I could throw them nicely, they weren't ruined in one bite and my small dogs do just fine with them.
