I would guess nothing at Ra has changed. The diference is between you and me and how we define things.
The anodize on My Ra Twisty tail is perfect but the head part isn't, I bet you never noticed the specs, but they are probably there. Since I can't twist it one hand I wouldn't consider it "butter-smooth" but you might. The only "butter-smooth" light I have had is the FF3 with brass threads, everything else pales in comparison. Raw aluminum on raw aluminum just won't ever be "butter smooth" on any light IMO.
No the anno really is perfect. There's no silver specks showing in the head. Only 3 silver bits showing in the tail piece. But my serial is in the low hundreds so I assume quality went down as production went on. Mine actually is buttery smooth in twisting and I can operate it with one hand. Raw Aluminum on aluminum can be smooth if the threads are big/thick enough and a thick enough lube is used.
The o-ring is what is stopping the one handed operation due it to being thicker than what is required/designed. I didn't change out my O-ring I just use some premium PTFE based lube called "SuperLube" and it works great.
