The Guard is my main putter. Back in the day I used to putt with Ching Tanks and shifted to Discmania P2's when I re-entered the game a few years ago. After trying out several Trilogy putters, I stuck with the P2's until the Guard came out. Once I got my hands on the Guard, it was immediately put in the bag. While I usually like softer plastic in my putters, I was able to adjust to DD's Classic plastic relatively easily and eventually was able to get Guards in Classic Blend which are in my bag now.
For me, the Guard is just a point and shoot putter. It just meshes well with my putting style and I just make more putts with it. In the past week, I have acquired some Moonshine, Prime, and Classic Hybrid Guards to put them through some test runs. So far, the Classic Hybrid plastic seems to be the best feel in my hands and the Moonshine will tested out as a thrower.
