OK, so...here is my take after 50ish throws with a Piranha: If you want a disc that you throw like a big bead Aviar that will fly like a big bead Aviar that isn't a big bead Aviar, the Piranha would be a Hell of an option.

I started out throwing it with a Rattler, but I had to put so much more hyzer on a Rattler to get similar lines that it was apples/oranges. Once I started throwing it back to back with a KC Aviar, I was pretty much making the same throws and getting the same results.

Sounds pretty useless. Might be more comfy to flick than a BB Aviar though.

It's kinda fun to take a full pull on a lid, release it flat and not have it flip. All of the other lids I throw I have to throw with hyzer to keep them from flipping.
