I used to play using the Phase 1 darts. Really had a hard time since my darts landed severely pointing down. Also, I tend to hold the dart just behind the center of gravity, using a pencil type grip, had trouble controlling the wobble. I switched to the Silica Apollos (that I planned to use before using my Phase 5's, as a cheaper alternative), that are about 42mm and practiced using them. The short dart fit my grip and I was able throw better with less wobble and the darts landing pointed upwards or parallel to the ground.
