In reply to The Ex-Engineer:
I thought most triple rated thin ropes have unicore construction these days? I'm surprised the Volta doesn't considering the way it's marketed.
I use an Edelweiss Performance 9.2mm which is triple/unicore and claims to be everdry, but I've used it in the pissing wet and it got completely waterlogged. I got soaked abbing on it as the rope passed through the plate and water got forced out of it onto my legs/feet similar to the way those old rolly machine things worked by forcing wet clothes through a pair of rollers.
