Want to Buy WTB - 11" roll of supra endura f surface.

Looking for the old stuff. All the outlets seem to have already replaced it with the vc.

I recommend purchasing minilab paper which is still optimized for optical exposure. Check ebay.

huh?

All minilab paper (Royal Generations, Edge, etc.) still works with enlargers because some minilabs expose optically (haven't gotten the VC digital ax of death.) The optical characteristics are nearly identical to supra, within 5cc blue-yellow each way. The only consideration is that Edge is slightly thinner than Supra. Both backprints are different as well. There's some Royal Generations paper up there right now for fairly cheap, though it is a tad old.
