The Thrasher is a high speed driver with an easy going turn for maximum distance at lower arm speeds. With the same flight ratings as the Hades, the Trasher is still known as the more understable of the two, providing long range distance for minimum effort.
These are Discraft's bottom-stamped white ESP discs, specifically crafted with the disc golf dyeing community in mind.
About the plastic: ESP plastic is a high performance plastic excellent for both beginners and pros. It has a great amount of both grip and durability. It will gently beat-in over time. Initially it starts off closer to Star plastic from Innova, but a bit more stiff. These are some of the swirliest and most beautiful discs on the market that just seem to get better and better the more you throw them!
