The TOMB is a flat-topped, low-profile, putt-and-approach disc with a comfortably smooth, beaded rim. The Tomb has just the right amount of stability to cover ground while threading the needle on approach shots, whether thrown forehand or backhand. It can also be used as a crossover mid-range, driving putter, or to hold the line while putting for distance or in moderate winds.
The X-Out, misprint, or factory second is a disc with either stamp flaws or cosmetic flaws in the plastic, so they are sold at a lower price. Infinite S-Blend is the equivelent of Innova Star plastic. This is a premium blend that provides excellent grip, a smooth release, and high durability. The Swirly S-Blend has decoractive, multi-colored swirls for added visual appeal.
