The Sentinel MF is unique among midrange discs. Its rare combination of speed and fade make it perfect for the following situations: low ceiling fairway drives, against-the-wind approaches, skip/fade up-shots, and “reverse S” approaches. Millennium is the original premium plastic, which is often referred to as our “base” or “standard” plastic. It combines precision grip with a scuff-resistant surface. Millennium plastic offers the durability required to withstand wear and tear out on the course while being offered at an affordable price.
