i mean this light is like one piece, head and body the same diameter but that is like most flashlights on the market. The SC51 was amazing because the head was wider then the rest, nice curves and smooth surface, all in all the light looked beautiful. This one has no curves, it looks a bit more ordinary in my mind, the knurling and the edges look aggressive, curves always look more organic and softer to the eye. Sure the knurling has a sense but its not beautiful. Sometimes i just want to hold the H31 in my hands because its a nice smooth feel like a stone. In my mind the SC80 lost a bit of its organic and unique look
