at the risk of wasting bandwidth, here's a view from when i tried it with a higher stretch resistence.  it's good still, but i think i'm gonna leave that setting alone for a bit.  stretch here was 100.  by the way the cloth is restrained only on the very ends of the tube (off camera a ways down) and both frictions on the cloth are at 0.

go that way really fast.
