Price, high security, low weight, great choice!
I've got this double rope. Really an excellent choice for trad and ice climbing for extra security. Climbing with double rope gives you quite a bit more options and Beal makes a very competitive half rope in the ice line. I use it for trad climbing too on free climb routes. You can't beat the low impact force / weight comparison. Handles really nice and smooth. Ropes are several years old and they still feel really good, no weird spots.
