Axiom says of the Proxy:
"The Proxy shares the Envy mold’s core, lending the same low-profile feel and solid grip, along with a short wing width and wide flight plate diameter for superior glide. The Proxy sets itself apart from the Envy with a remarkably straight forward-fading finish. A bit of high-speed turn potential allows the Proxy’s lines to be manipulated over a broad range of power, and helps less powerful throwers achieve straight putter drives."
Electron is Axiom's baseline plastic, and the Electron Firm variety is the most durable, and less flexible of the Electron blends. It is primarily formulated for putters.
