You know, Neutron Proxy's aren't exactly hard. They're softer than Neutron Anodes and Ions. I wouldn't want the flight plate any softer, but I guess the rim/OM could be.
I think you're going to really like the Proxy, especially for throwing. First time I threw it, it was like "you're kidding me"! It's dead straight right to the ground, powered up or powered down.
I've been saying this for weeks. The current run is pretty soft when it's not freezing out.
I would like a soft for winter golf and maybe for extra grip in the rain.
