The TaylorMade Spider ZT Counterbalance putter is engineered for players who want enhanced stability through a slightly longer shaft and a heavier head designed to increase MOI and promote consistent, repeatable strokes. A high‑density 303 stainless steel front section pairs with a lightweight 6061 aluminum back to create a high‑MOI foundation with precise CG placement and extreme perimeter weighting. The low‑torque KBS shaft is bored directly in line with the CG with slight forward lean and toe‑up balance to encourage a steady stroke and minimize added loft at impact. An improved cambered sole sits flush against the ground for cleaner alignment, while the milled True Path™ alignment lines help you center the ball with confidence. The Pure Roll™ insert, made from Surlyn and aluminum, features 45‑degree grooves that promote forward roll with enhanced sound and feel.
