The black vs isn't a French Open "edition". It has the RG logo but is otherWise a standard offering. Like the natural color it uses BT7 tech which makes it stiffer than pre-BT7 Touch. No other difference besides color.
If you want a softer feel try Wilson natural gut which some say is simply pre-BT7 Touch.
I'm about to try Wilson with 4G crosses.
