robj, the mold is similar, and so is the flight characteristic. I would say that the QMS is between a Roc and the Coyote in flight characteristic. The QMS is more high speed stable than the Coyote, and more low speed overstable too.
Sounds more like the Aurora MS -- which i really like. For some reason it's the perfect forehand disc for me.
if i can get you back on throwing understable plastic nose up to fly straight (rather thsan flipping) -- is the JK Valkyrie easier to throw nose up than the Sidewinder in terms of it requiring less finesse? (i think you once mentioned some discs which were less nose angle dependent than others...?)
