I think andean silk is FABULOUS. I don't know if shine worsted would work; it's *really* heavy and strechy.
ETA: elegance from KP is really nice too, even softer than andean silk. It's a DK weight though, but you might still be able to get gauge.
Also, I have the color cards for all the KP yarns, and they are showing up MUCH darker on my monitor than they actually are in real life.
I don't know if that makes a difference to anyone, but ...
