Rather than stitch, clamp, heat-shrink, etc., why not simply tie a loop in an empty section of the hollow paracord? Use the weed-whacker plastic only in the coil area, from knot to knot.

A knotted loop without the plastic core is soft enough to attach any terminal clip or ring you like, as you would attach/remove a torpedo weight to/from the end of your line.

A simple paracord loop is nothing to scratch or snag, and nothing to corrode, rub, slip or break.

To secure the pole end, it's easy to wrap a strip of 1" wide strip of Velcro through the loop onto the pole for a soft and out-of-the-way connection.

For convenience and versatility, I would make both end loops the same size. With paracord, I think a loop made from a single overhand knot is good enough, smaller and neater than a double overhand surgeon's knot. For a single overhand loop, a 9" tag end will produce a neat 2" loop.

No fuss, no muss.
