The Pestilence is a really fun disc to throw, it is very understable and requires little power to get the disc to flip up and do a drifting turn.  It definitely has a turn of -4, if you can throw over 350ft you might have some trouble keeping this disc from becoming a roller.  That said it is a great roller disc, it's very easy to get down and roll off of a flat release.  I think the disc has good distance potential, I was able to find some crazy distance lines throwing the disc off a very deep hyzer and giving it a lot of height and watching it turn over and glide for days.  The Petilence in radioactive waste is more overstable than toxic waste (though still pretty flippy)

Just hit my first ace in years with this bad boy on a dramatic anhyzer line. Last year I hit a new PR for distance while Hyzer-Flipping this. Not for everyone for sure, but I have loved mine.

I purchased this disc in the glow version of the radioactive waste plastic.  The glow only lasts for a second, then is completely dark.  I can shine a UV flashlight right on the disc, and as I move it around you can see it going dark again after literally just a few seconds as I move the flashlight on the disc.  It turns really hard and seems super understable.  I can't help but like the disc however, maybe because of the gimmick, even though the glow fades so quickly it's totally worthless as a glow disc.
