In reply to pancakeandchips:
Had a pair of aramid sheathed, Edelrid protect pro starlings 8.2mm for couple of years, they get furry real quick and my pair are the most twisty ropes I've owned, tricky for multiple pitches (had to tie one rope out to get rid of twists) and rapping can be fun, more theoretically (cant say it effected me) they also have quite high impact force.
Improving cut resistance is clearly a good target but not sure they quite got it right yet.
Really innovative company and I will probably buy their next iteration of this tech
