It worked!!!!! I love it when I learn something new. I don't know if it was this thread of the "lightening your tools" thread, but someone suggested zip tying the cassette to the spokes. I just gave it a try with my typical removal nut with splines, and the Leatherman Crunch that I carry. It worked!!!! Easy breezy. I gave up a hypercracker for a length of heavy cord with a knot, but now I'm down to a few zip ties to use as a chain whip.
