As others have said, the Arista 125 acts like FP4. I've shot several boxes in 4x5 and have been very pleased with the tonality and other properties. I'd note that at current prices it's only slightly less expensive than Agfapan 100, and therefore probably not competitive against the Agfa if you can find that locally. Pity they stopped selling their large-format Delta-equivalent just before I was ready to order a box.
