If memory serves me, Tom Hubbard gained about 1.5” in length and about 0.5” in girth, most from hanging and whatever manual stuff he was doing. He did all of this before we had any Bib hangers. At the time, it was pretty much pay $150 for the Grip (which relied on vacuum to hold the hanger on), try to make a latex swimcap work, or use dreaded loop/noose.
