A question for all you string makers. I've recently changed from using B50 to B500, only because BCY has a greater color range. One thing I have noticed is the black B500 that I've bought is not very colorfast. It's almost as if the color has leeched into the wax and the wax has dried out. As soon as you start working it, your fingers are covered in lots of small black specks, and the string is almost gray in parts. Compared to the B50 which was a nice glossy black, this stuff is poor.
I'm not trying to knock BCY, as I bought this from a third party. I'm just trying to figure this out for my own piece of mind as well as my customers.
Have I been sold old, dry stock, or is this something I have to live with?
