The Realm is probably Gateway's closest driver to that Destroyer-type disc.  I've thrown their three latest distance drivers, the Ether, Realm, and Spell.  The Realm sits in the middle of the other two new drivers in terms of stability.  I think this is a very good 12 speed OS distance driver.  It feels very good in the hand, and both of my Realms (I have one in Diamond and one in Cobalt) have a good amount of dome to give it that extra glide.  My Diamond Realm is still fairly new and not that beat in, and it has a pretty strong overstable finish to it.  Not as beefy as the Spell, but it reliably fades out at the end of its flight.  The amount of overstability gives the disc good control and allows me to throw different lines with it.  It will generally fight out of an anhyzer flex shot, and its good amount of torque resistance makes it a good disc for forehand drives.  My Cobalt Realm is noticeably more understable out of the box, and has a decent amount of turn.  It flies more like a Wraith.

This is a good all around distance driver, I have found that the Realm is not quite my longest driver, I can usually get more distance out of a 12 speed that has a little more turn like an Emperor.  I'm interested to see how this disc flies once it beats in and develops some turn.
