I got a reply from teufelberger
They are very aware that the akimbo essentially fucks drenaline. They have no control over what rock exotica say is an approved rope. Despite how damaging the akimbo is to the drenaline in actual use, rock exotica seem to be fine approving it for use because it seemingly clears load testing. There was no comment on the core strands pulling out of the salice. They're replacing my drenaline with a length of xtatic which they haven't had reports of the akimbo negatively affecting. Although i havent heard anything back once i gave them my shipping details so it'll be interesting to see if they actually follow through. They did seem to agree to replacing my rope a bit begrudgingly, replies quickly turned into one word scentences without any formality such as a hello.
Assuming that they might not keep their word and replace my drenaline I've cut the salice off, it had three core strands pull out of it from use, i pulled the core strands taught from both ends to try and get rid of the horrid lumps, milked it both ways and sealed the ends. It's somewhat useable now, still has lumps but they at least don't stop me dead on decent leaving me stranded.
Again, really quite disappointing, after looking at the core strands they seem to be excessively twisted, more so than any kernmantle cordage i've had apart. I'm guessing this is the reason why the lumps form and why it has so much bounce along with why it milks so much. Given xtatic is well...more static I'm amssuming the core strands are less twisted and won't suffer the issues drenaline has.
