Bob,
I've got a matt silver finish Shoei lid.
Plus point

is that scuff marks & scratches don't show nearly as much as they do on your normal shiney finish lid.
Minus point

is the road grime, general dirt and splatted flies seem particularly attracted to it (but I'm an all weather rider). All this is easily removed, but the matt finish shows the dirt really quickly in comparison to a shiney finish. Also you don't have the same satisfaction from the matt finish that you get when you've cleaned a shiney lid.
To put it bluntly, I wouldn't buy the same again. The only reason I bought the one I wear now is down to the fit, it was way above the comfort level of the others in their range. And for some reason I can't now find an Arai that is comfy - although I always used to!
