* Plain webbing would roll even less. If I had a monohull I would opt for webbing and annual replacement.
* The carabiner will slide better on rope. Webbing or webbing with a core is not used in industry or by climber in this application. webbing over spectra core is common for lifting slings, so the idea has president.
* The price is excessive.
* It is impossible to inspect the line, as the rope is not visible. This will lead to premature replacement.

Very high tech with some benefits, but still a compromise, I think. I have probably done more time than anyone on the board climbing (a guess, but it is a lot spread over 25 years, including small cliffs, big mountains, rock climbing, and ice climbing) and I don't think it is a system I would take up a mountain or use in an industrial facility.
