You know, that's a good question. I don't know that CRK ever crossed patterns between CGG Sebenzas - Meaning if a CGG graphic like "Website" or "Crosshairs" (or Acoustic) was made in both the Classic and Regular styles.
Of course I'm referring to just the CGG Sebenzas, not the Unique Graphic ones. There are several examples of the "Night Sky" graphic used on each Seb style, for instance.
Looks like some internet sleuthing is called for!
