This is my favourite disc ever and the cornerstone of my bag. I use it for virtually every shot - upshots, panning anhyzers, spike hyzers, even spin putts if I am having trouble with my typical push putt. The plastic an mould combination is perfect for me. The disc is also board flat and releases perfectly on both forehand and backhand. The K3 Kaxe starts out very OS and it did not make the bag for many months before I finally beat it in. Now I have 3 in the bag in varying degrees of wear.
