I highly recommend reading Owen's review here- I totally agree.  By numbers you'd think this is a zone and it so isn't.  Much more glide much more us.  I actually really like throwing it as a stable tweener between like a PA1 and a mid, but it simply doesn't have that hook that 2.5 fade suggests.   It's much easier and straigher than that.  But, it turns out it has a place in my bag and I love throwing it; it's just very misnumbered in flight ratings.

Although the prodigy rating of 3 feels right, but 3 doesn't equate to 2.5 fade and neither does this disc. 

This review is for the 400 spectrum.  Beautiful plastic-- very swirly and gummy that gives a nice grip in the hand.

I was looking for a disc that was ever so slightly more overstable than my Eclipse 2.0 Envy, but not quite as overstable as my ESP Zone.   Long story short, this is not that disc.  The numbers are completely off for at least my particular run of 400 spectrum plastic (Christmas 2021 stamp).

This thing is gliiiidey.  In a direct comparison between this and my Eclipse 2.0 Envy (which is a more straight and glidier run of Envy) I found the PX-3 to constantly fly about 20-30 feet further.  It still has a predictable finish at the end, but it's nowhere near the 2.5 that Prodigy rates it as.  It actually might be a hair less overstable than my Eclipse 2.0 Envy.  I'd say it's somewhere between my Cosmic Neutron Pilots (2/5/0/1) and Envy (3/4/0/2).  I'd give it 3/5/0/1.5.

It's a great flight if you're looking for a general workhorse throwing putter that you can cycle through from slightly overstable to understable, so I rate it highly there, but it's definitely not a consistent overstable putter like a Zone or Stabilizer or Harp.
