Go read my review on the Eclipse Proxy, and you'll see that there aren't many discs I love more. It's definitely a top 3 disc in my bag and it never comes out of my bag. I had recently picked up a Neutron soft Proxy and was a bit disappointed that it wasn't the undrstable brother to the Eclipse Proxy and it wasn't very soft at all. So, I found this electron hard Proxy with the hopes that it will beat in a bit and become my understable brother to my main Proxy (Eclipse). Today was the first round I played with it, and I hit band on a tight wooded hole; it was so close to an ace and only the 2nd or 3 throw with it. I love the grip of this plastic, and I have a feeling she's going to be staying in my bag! 

Super straight flight with a forward penetrating fade. In electron soft this disc will finish with a turn, in eclipse it finishes with a fade, in cosmic electron firm it finishes straight for me. 

The proxy is a very special disc for me. I got one in plasma in a mystery box and almost immediately fell in love. It feels almost exactly the same as an envy in the hand (which is in my opinion the best throwing putter ever made), but it offers a different flight that compliments the envy so well. While the envy is straight to slightly overstable, I've found the proxy to just go straight. If I throw it flat with about 60 percent power it won't have any turn or fade at all and will fly completely straight on the line I put it on. If i decide to power up a little bit more the proxy will turn just a little bit and never come back. This gives two different shots from what I can get from an envy all while maintaining the same hand feel. 
 

I think the proxy is a perfect straight putter for anyone who likes a shallower feel either for putting or throwing and I cannot recommend it enough. For beginners I would expect it to fly more overstable but still very controllable and still mostly straight. If you throw putters often, and if you like the envy please do yourself a favor and pick up a proxy. 

My favorite throwing putter and approach disc.

I use this disc all the time for woods drives up to 180 feet.

I also use it for most approach shots.

It's definitely understable but it never flips over on me - it always finishes straight or with slight fade.

I don't know if the GYRO overmold works or is just a marketing stunt, but this disc keeps its angle well at lower speeds. It also maintains its speed thanks to the thinner profile than some other putters. The combination makes it very useful for shots in the trees or with low ceiling - you don't need to worry about the disc curving in any direction, you just trust it to go where you threw it.

I would definitely buy it again if I lost it.
