Mystic is a pretty good mid. The Karma, not so much. The mystic is a smaller diameter mid that is really straight. A great mid for heavily wooded courses. The Karma is trying to be an Elemen-X, but failing miserably. If they could eliminate some of the dome on the karma, it would be a better disc. The Scout is also a pretty good mid. Very straight with a slight left finish(RHBH). If I was going with a Gateway mid line up, it would be Demon/Warrior/Scout/Mystic.
