For the summer I moved on to the Z Drone for a slightly better glide but once the cold weather moves back in for good, the FLX Drone is a staple in my bag. Great for hyzer driving and approaching on anything under 300 feet. When I need to get up and over obstacles with a finishing fade to the left, nothing handles it or is as forgiving as a Drone (if I try to get over obstacles with anything else, they often land straight ahead instead of around the obstacles).
They are also great for skipping off the ground to get a hard, predictable left bounce. I use this bounce at Plymouth Creek #5 and Blue Ribbon Pines #26 if you know those holes. When worse to comes to worse, FLX Drones make a good putter replacement, especially in windy conditions.
The combination the Drone's overstableness, the nigh-indestructibility of FLX plastic, along with the FLX Plastic great wet/ cold weather grip makes this a must have disc.
One thing I noticed though, and I do not know if this will really make a difference with people, is that the 2008 World FLX Drone is far firmer than the LE FLX Drone from 2008. I have not fondled a 2009 FLX Drone, so I do not know how they compare. The World Edition flies a lot better than the LE.
