Echo Star Archon (175g) - I have never really figured out what this disc is supposed to do. Maybe I don't have the arm-speed for a speed 11 driver, but it doesn't really ever do much other than fade. I also don't really find the glide to be noteworthy and certainly less than the 5 rating. As another reviewer mentioned, it is an odd disc to hold. Needless to say, it hasn't had any time in bag following a few field sessions with it. 

This is one of those really odd rims.  I like the disc's flight but hate the rim.  This is one I would recommend you hold before you buy.

The Echo Star Archon is a nice disc! I owned one as a replacement for the Star Archon that I lost, and I loved the flight out of the box. 

The Star Archon offers a straight to understable flight with a dependable fade at the end. The Echo Star Archon is just a little more understable than the Star Archon. The plastic is slightly different but mostly feels the same as the Star Archon.

The Archon has a really flat top, offering a different feel than it's similar disc the Champion Tern. If a you like a valkyrie and beast, then the Archon might be a good disc to try out. The Echo Star Archon will be just a little bit easier to throw if that seems to be what you're looking for.
