I've kept Supra Endura at room temperature for a year with no degradation. Supra II and III did degrade.

Good for you! But in printing editions I notice slight yellowing of the paper base in as little as 4-6 months. Very subtle, but definitely there. But it's a moot point and not worth quibbling about.
Ya think?I would like to believe that the temperature is not just put there for fun.
