KNITTERS: I Need Your Feedback

OK, knitters, I need your opinions:

If you had ~600 yards of a luxurious sportweight merino/silk blend, what would you want to knit?

1. A stranded colorwork cowl
2. A slip-stitch/mosaic colorwork cowl
3. A small colorwork shawl
4. A small lace shawl
5. Something else?

Please weigh in on this.  Inquiring minds want to know.
