Supra III pre-dates Endura, so that will be pretty out of date. I'd skip it ( the 5 x 575 roll).
Basically any later supra endura in sheets is still worth snagging. I am sitting on 4000 sheets or so in various sizes.
It lasts a long time, even well past it's out-of-date range. Even longer if you freeze it I think. I am using some from years ago and it's still fine.
