Great price, great rope!
Me and a friend of mine got a pair of these ropes from Backcountry.com a couple of months ago. We've been using it on weekends' climbing days. It's been a great rope 'til now. Also the rope bag is very useful, the tarp helps to evy the rope gets dirt. Just the nylon loops sewing seems to be a little fragile. It seems it'll go unsticht if you put too much weight on it.
Otherwise, contrary to what appears on Backcountry Specs, the rope DOES HAVE the center marked with a pair of black bands around the center section of the rope.
A great choice from a great brand like Mammut.
