I really don't know, there is so much going for the Samson Arbormaster line, why is everyone looking for a small piece of what it has in other ropes?
It needs no break in, (well it is different after a few climbs and didn't have the friction hitch slip like new HiVee.)
It is 8,500 tensil, gee even with a few nicks and lot of fuzz I'm secure.
It can be spliced at both ends! Dah, that is telling you a lot about the superior construction.
Relitive to it's size it is light.
OK, you want a double line to foot lock with up to your TIP and then set your work line, then one of the other lighter lines is what to have xtra in your arsenal.
There is nothing out there that does so much.
