The Slammer is the more overstable addition to the line of Dynamic Discs putters. Featuring a thumb groove on the outer edge and a small bead along the bottom of the rim, the Slammer feels like an old friend. Able to hold up in about any wind conditions, it will maintain stability throught its life in the bag. Prime plastic has an incredible feel and excellent grip even when the weather compromises your hold on your favorite disc. Prime offers an affordable line of plastic for players looking to add a new disc to the bag. Prime Burst is a very unique looking plastic that has a mixture of 2 or more colors bursting from the center outward. All colors offered are the primary base color only and each one is entirely unique!
