So there is lots to think about and the Serenity would never be my choice for climbing on rough gritstone or certain other high friction rock types. I also wouldn't bother choosing it when a short walk in means I don't need the pack ability or weight saving they offer. However, when faced with a heavy pack, a full on mountain day or a long walk in, the Serenity is worth every penny and the Serenity is currently my first choice for both personal and professional use on long multi-pitch and mountain routes. I have also found the Serenity lasts well if managed carefully and the rope is a dream to handle providing the thin diameter is factored in. Well done to Mammut for producing another innovative and high quality product. So, if your budget allows and the rope suits your requirements, I would really give the Mammut Serenity a close look. You won't be disappointed.

I took numerous whippers on the way to eventually redpointing the new line and haven’t noticed any unusual signs of wear on the rope. It’s worth noting, however, that Mammut touts the Serenity as a specialty rope “designed to favor weight-savings over durability … i.e. redpoint attempts or super-light alpine ascents.” If you’re looking for a dog-a-thon workhorse, pick up a heavier, larger-diameter rope. But for those times when you need a little edge, whether in the high mountains or on a particularly nefarious project, check out Mammut’s Serenity. I’d suggest forking over an extra 20 bucks for a 70-meter ($250) halyard and then pimping it to the fullest.
