Reading through the "what finish do you prefer" it seems like the general consensus is that the xmetal finish is most preferred. But my question is: does the xmetal finish start off "grainy/rough" textured when it is brand new and then smooths out over time to feel more "silky"? Or do the different generations of xmetal have different textures? The reason I'm asking is because the first pair of xmetal finished mars (from wayyy back, i think 1st gen) are very grainy. They have an almost fine grain sandpaper feel to them. But I haven't worn them so I don't know if this texture smooths out over time. I had a chance to look at a pair of xmetal/ruby Juliets at the the ostore and the finish was more smooth and silky. From pictures I've seen, the first gen plasma finish looks to be rather rough and grainy as well, where as the current gen plasma (which I own) are very silly smooth. I'm just wondering which gen of x metal frames to hunt for.
