A friend let me try his King, at the time it provided me with some of my best distance. Needless to say I picked one up the next day; Elasto plastic, 174g. I loved this disc when I first got it, great S flight path and tons of distance. As I started to gain more arm speed and hit a few trees with the disc, the King became very understable. I started using the King as a turnover and hyzer-flip disc. I have a Frost Bolt and the Elasto King is extremely similar.

Both the Bolt and King are high speed, understable discs. They have larger rims, which I prefer. One major difference I noticed about the king was that when it turned over, it held the anhyzer line a lot longer, and wouldn't fade/flatten out as quickly as the Bolt.

I really like both discs, but since they were so similar I couldn't justify having them both in my bag. The only reason I chose the Bolt over the King was because it had been in my bag longer.

I definitely recommend trying the King, but expect it to be more understable than its ratings. I have also heard from multiple sources that the new Kings (11-1-15) are much more understable and super flippy, which I can definitely attest to. If I didn't already use the Bolt, the King would be in my bag. It is a really fun disc with great distance.
