The Anode is the second putter from MVP, designed to be a neutral-stable compliment to the overstable Ion putter.
Neutron Plastic is MVP's much anticipated update to the old opaque plastic of their early days. Grippy and every bit as durable as their Proton plastic, Neutron also features several high-visibility neon colors. The flex on this Anode is the firmer of the two types, which MVP previously called "Medium" flex. MVP now only designates the flex on their soft putters, leaving these firm types as simply regular Neutron.
R2 Neutron discs will fly the same as their Neutron counterparts, but with the benefit of being more eco friendly. Do your part for the environment, and give R2 Neutron discs a try (available with the Anode, Ion, and Spin initially).
