The Innova Nova, a straight-flying Aviar type putter, utilizes two different plastic blends to provide a unique flight and feel. The outer rim consists of a very soft grippy plastic that grabs the chains. The inner flight plate is firm, but tacky. This tall two-piece putt and approach disc is described as having the high-speed stability of the Big-Bead Aviar with minimal low-speed fade. It’s the perfect finesse disc that can handle the power of “modern players”, while providing precision accuracy. The unique thing about the Innova Nova compared with other over-mold discs is that it has slits approximately one inch apart throughout the rim. 2/3/0/0. Innovas XT material is a midgrade plastic that feels similar to DX, but that is substantially more durable. This is a tough grippy blend that is popular for putters and midrange discs.
