Here's a question for @GTHintz ...

You're familiar with Dean Markley Blue Steels. I know they used to come with black ball ends and white or light silver silk. Did they ever come with black ball ends but no silk at any time in the past?

I'm not too sure but older blue steel would be the first guess. I remember them with either black or very dark brown ball ends. I know during the transition period when they sold the old factory things got pretty random for a bit. Silk, no silk, silk on some, ball ends changed color.
