Definitely one more tape to add to my bin of tapes: various widths of kapton, various vhb mounting tapes, anisotropic electrically conductive 9703, and ultra-slippery rulon tape... all of which I never use of course.
I also have an "exotic tapes" bin. :)

For example, do you already have a toupee tape in your collection? :)
