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. With Soft plastic you won't have any problem with your discs sticking to the chains. The flexibility of this disc will absorb impact and makes it a great option for upshots on dangerous greens. Classic 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!
