Tri-Hot 5K is built to improve performance by reducing the amount of side spin on off-center hits. Achieved through a 303 stainless steel front section that includes the hosel and face area. This material has been finish milled to exact shape and weight, helping to keep the Center of Gravity forward, this keeps putts closer to the original line, with tighter dispersion, and a greater chance to go in on less-than perfect strikes. We have positioned massive amounts of tungsten behind the face in the toe and heel sections of the head. We've moved the Center of Gravity forward for improved roll, while also increasing MOI. Available interchangeable weights that you can dial in your head weight to your exact preference (weight kit sold separately). Legendary White Hot insert for better feel, sound and performance. Red Stroke Lab Shaft that features better performance. By shortening the steel section, we reduced the weight compared to the original Stroke Lab shaft. We have made it stiffer and more stable for even more consistency in your stroke and your performance. Tri-Hot 5K Rossie S
