I need a plan for the yarn

I have this gorgeous skein of Abstract Fibers, Alto.  392 yards of dk weight-ish yarn. In honor of the trunk show we are having at Westport Yarns this Saturday, I want to begin knitting with this skein.  It is totally out of my color comfort box and I love it all the same.

I’ve found two patterns that are a possibility.  Sleeveheart or Casu Cowl.  Please weigh in with your choice and feel free to post a different pattern option.
