Took the K2 & K3 Berg out to the local pitch 'n' putt this morning, along with a couple Zones and Judges for comparison. First impression is that the Berg flies like a slower, less glidey Envy. I'd say the K2 flew 1/2/0/2, and the K3 came out of the hand just a tiny bit faster and with a little less bite at the end. Probably not enough to call it a different flight rating, nor different enough to warrant bagging both, but there was definitely a slight flight difference. Berg was coming up about 30' short of my Judges when giving both a good rip. Similar distance to my Titanium Zone but with a completely different flight shape to get that distance.
Overall I liked the K3 better. Both came out of the hand really nicely on backhands. That tacky/gummy K2 plastic seemed to grab the ground just a little bit quicker, but not by much. The K3 felt MUCH better in my hand for flick shots, which is why if either disc makes the bag it will almost assuredly be the K3. I really wish I had grabbed a K1 rather than K2, since I'm not sure if it's the plastic type or disc shape that is causing me forehand release issues with the K2.
