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.

and the helicopter leading edge tape, I have a 50m roll I have used 3 iches of.

Bi-directional filament tape (aka "hexayurt tape") is a good one. Bonds quickly to most things, has absurdly great tensile strength as well.

I also have an "exotic tapes" bin. :)

Here's a list of other types of adhesive tape:

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

VHB has gotten me out of mounting jail free many many times.

This the kind of thing I wouldn't buy at amazon. It's small, expensive and mechanically simple. A good recipe for counterfeiting.
