Hi Michael.
I mentioned this to a friend this morning and he emailed the attached photo. Question answered I think!
Your comment re the 'stretchy' tape is interesting. I genuinely never encountered any problems at all. You may well be right about the double play thing. I think I only ever bought one reel of DP. I have some very old 5" & 5.75" reels of International in my collection and they still seem OK - no shedding.
Cheers,
Roger.
