The Infinite Discs Tomb is flat and beaded and will hold up to a ton of power. It is stable enough for forehands and backhand it will hold a straight flight into a moderate headwind. It is great to use off the tee or putting into a headwind and you need to trust the disc to hold up without being too overstable.
Infinite S-Blend is the equivalent of Innova Star plastic. This is a premium blend that provides excellent grip, a smooth release, and high durability. The Swirly S-Blend has decorative, multi-colored swirls for added visual appeal.
