Being at work today (GODDAMNIT!!!) I've had plenty of time to peruse their site.
The black is actually UV protected monofilm, and 0.7 is a racing score for 1st place.
They reckon with the UV protection you can even place the sail on grass and you won't get that moisture on the grass side like you do with clear monofilm.
Looks like well thought out, quality construction.

You can buy direct. I priced a 5.8 Sado at $AU640 delivered, customs would add 10% to that. I don't recall any other manufactures offering being able to buy direct (brave new world).
