Well, I spoke too soon. I've had the tape on for quite a while with no problems, but when I got to the trailhead at Glacier NP a couple of weeks ago, the middle pole sections were solidly locked inside the upper sections. Completely immobilized. The poles were useless, which is a big deal when your shelter requires poles for setup. I was able to use someone else's poles for the entire trip, but it could have been a showstopper.
To separate the sections once I got them home, I machined down a steel expanding anchor to fit the inner diameter of the middle section, expanded that inside the pole with a layer of sandpaper for traction, locked the expander in a vise, and worked the outer section. The sections still wouldn't separate until I sprayed penetrating oil between them to loosen the tape adhesive, and even then I had to work the outer section back and forth for a few minutes. No more tape on my poles!
I had tape on the lower sections as well, but I remove these sections to reduce the overall length for transportation so I didn't have a problem there. The poles worked fine just a few weeks earlier in Japan, and I have no idea what led to the problem (both poles suffered the same fate). The tape on the lower sections seemed fine.
Be careful!
