I have a lot of boxes as well, grades 2 & 3. I've never liked the base much for printing normally; it's too creamy for my taste.
It does lith. In fact, I found it was one of the contrastiest papers I've ever lithed with. If I recall, I was having to hit it with 6-7 stops more light than a paper like Agfa MCC 111 (which I like in lith). In hitting it with this much light, the colour you got was spectacular. Spectacularly bad, in my opinion. Neon orange/green, with that creamy base. That was in LD20 and homebrew formaldehyde free developers.
With that said, if Guillaume uses it and likes it, it's worth another shot. You'd certainly need the right image!
