Do any of the versions have a center mark?...
Do any of the versions have a center mark? Specs say no, but one pic looks like it has one.
I'm fairly certain that for this particular make of rope there is no center mark. The various "versions" offered for the Flash vary strictly in length and color (with superdry option). Otherwise they are all the same.
Mine has a center mark. Two black sections about 6in long mark the midpoint.
