Drone: approach shots out to 250, in either a serious headwind, or hard left dog legs, short fh approaches with a hard right, and big skips.
Zone: headwind putts, short hyzer approaches, long flex out putts, shorter forehand approaches
Almost the same disc but one is longer, and one has very little skip. Between not having them, and using them, they'll always have a bag spot, even just situational shots
No skip with the Zone?
