I've had my 2027XVV since 2001 and was aware of the 2127X in matte black for the Japan market. I've kept a pretty close eye out for any of these. My 2 cents is it's a refin.
I had the same concern as yours. I've only played one for a brief period of time, but it felt fine. Comfortable. I'm coming from a RG 1527, 7620 comfort level.
These are great! I wanted one of these when they came out, Good score! Most of the ones I've seen out there are either beat to s**t or way too expensive.
