There two thicknesses available commonly, others for stained glass craftsmen. Either of the two common thicknesses will last longer than your interest in the current track, and that's a fact. I stripped 17 year old tape from my current track when I started work restoring it, and it was very nicely stuck down, and NO wear-throughs, which amazed me. My old track had a place where the tape had corroded a bit and I retaped that section, but I could just as well have sanded or Brasso'd it to bring back full conductivity. If I wasn't using that as an excuse to re-rout the slot in a different path, I might not have re-taped at all.
P.S.- I should add that what is critical is using fresh tape. I do stained glass art, so I have a bunch of this stuff at all times, and I recently learned that the glue can dry out, making it peel up within a year. Just don't leave the package open for years at a time!
