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. The Classic Blend plastic is the perfect Medium blend from Dynamic Discs. On firmness it falls right inbetween Soft and Classic, giving your putter the perfect grip and feel for sinking big putts.
