Firm Electron Ion
From MVP: The GYRO™ putter lineup is more complete than ever now with the Electron Firm Ion. The Ion was MVP's first disc ever and fans have been waiting on this plastic release since the beginning. Electron Firm is the most stiff version of this popular baseline style plastic, built for the demands of warmer weather and players who like maximum resistance in their plate. The full range of Electron is now available in the Ion - Soft, Medium, and Firm - with all providing a great chalky feel that promotes a solid grip.
