Funny enough, I happen to own both a calorimetry and a drop stitch ribbon scarf.
I haven't touched the scarf since I cast off. Calorimetry however, I wear whenever the weather hints that it wont kill me to wear a wool hat/headband thing. Also, I love the Calorimetry because it's a loophole to the "No hats EVER!" rule at my school. (On those couple of days in Florida where your ears do not want to be bear outside.)
I can knit without looking, even hold a conversation with someone, keeping normal eye contact, while knitting on autopilot. I dunno...for some reason I really like to watch the knitting, and the fabric unfolding ect. I'm all about the process.
Doubled-up cascade fixation (or esprit from elann, which is about half the price) sounds like it would work good. Although it's cotton/elastic, not acrylic. (Which actually sounds better to me, but different strokes.)
