One benefit of the black vs: you quickly see how consistent you are. Where my VS mains intersect the 4G crosses the VS turns gray with use (and evetually frays there). After just one session you'll see if your impact points are consistent (and after much hard work over the last two years I'm very proud to say my SB's center gets well worn while the perimiter remains nearly pristine with the writing on the VS perfectly legible.).
I fully agree with PVAudio about black Xcel vs regular Xcel. We tried black Xcel in my son's frame when we first bought it. It felt nothing like regular Xcel which is one of my favorite multis. It felt stiff and dead where regular Xcel feels almost plush and powerful without being overly lively.
