The "Promising" Rope by Sterling... Triad

Has anyone tried the new rope by Sterling "Triad"?
Quite static; advertised to be "round"; twisted cores, sounds bad, all the ropes that have it, after much use, core twists contrary to cover, making the rope want to twist on itself. Starting to happen with my Kalimba, but Drenaline was far, far worse.
Maybe I'll buy a sample and compare it to the Beal Access 11mm
Kalimba flattens a bit too much, twist internally, not as good of a grip as 32 braid, and is a bit too stretchy.

I really like that Beal Access 11mm. Keep us posted if you get the Triad.
 
I only use the ZigZag Plus in MRS, 90% of the time I use the Petzl Naja as a TIP, 10% natural bark.
Yes, I understand using MRS especially with a pulley, will allow the core and cover to twist independently of each other.
But, if a rope was made like the Beal Access, cover and core would be permanently synchronized.
In Kalimba's defence, it will only naturally twist about 3 full twist at 60feet, with just weight of ZZ, only.
DrenaLine was at least 10 twist at that length, with the ZZ.
Beal Access has never twisted, at 60ft or more.
 
Here is a picture of the Beal Access, just after cutting the cover, parallel to rope. That gap between the cut sides, is indicative of the cover tension and core compression, to keep the rope more round, under pressure.
Although each of the 12 cores are "twist braided", they are placed parallel together, which may reduce tendency for the core to twist, within the cover.
Furthermore, there is an adhesive applied where the core and cover contact, it is hard to see, but I had to pull each core, (that sufficiently contacted the cover) off the inside of the cover. Which according to Beal, is their UniCore design, to improve safety.
"Now equipped with our UNICORE innovative technology, it has reached a new level of safety while remaining easy to handle and light enough to become a must-have for work at height."
Makes sense, as natural tendency of a rope twisting, and flattening, I've found to be a safety issue.
The cover over core compression/tension keeps rope round, and the cover/core adhesive eliminates independent cover/core movement.

I remember something in a test vid where IIRC bonding the cover increased the rope's resistance to abrading and breaking over a sharp edge (?).

edit - prevented large exposed core section cutting on an edge after de-sheathing, I think some fresh adjacent sheath absorbed additional abrasion to more resist cutting
