This is a great trad multipitch rope. It is holding up very well after dozens of climbs. The bi-pattern version is amazing, no searching for a middle mark and much easier to tell which side to pull for rappels. Not too thin or thick, goldilocks would be pleased. Best of all, its inexpensive.
The number one thing needed for a rope to do is to provide me safety in an anchor system. In some circumstances it is the whole system. All other cosmetic or personal preferences about ropes are moot when all we need is for that rope to be a reliable hard point to the gear. For those reasons i make this a 1 star review. When I took this rope out of the packaging to flake it out the first time, it had NUMEROUS soft and flat points that failed the 180° roundness pinch test. Any product can arrive defective but this issue is also mentioned in numerous other reviews on this website for mammut rope. Mammut/REI: Why not recall this product and quit wasting our time? Before someone gets hurt!
