the xs is a great disc the x and z fly different though. the x starts out straight and beats into a sweet turn over disc and roller. the z starts off a touch over stable and beat straight holding the sweet spot for a long time. If they were made in the 150 class they wuld still be in my bag. XL kick ass as well. anaother disc in this speed range to look at is the assassin from gateway.
