Actually, from what I've read about this film, I am way more concerned about the apparent fragility of the emulsion during processing (and the fact it's on two sides) than I am about the spectral response. I don't own, and have no other reason to own fancy tanks and hangers in 8x10, so I'll be wrestling with plastic bags or smooth trays or whatever.
I have no illusions that the results are going to look "exactly like Delta 100," but I expect to get some useful results using my recently built pinhole camera. In my own quirky opinion, the pinhole process is riddled with enough compromises that one more won't matter. The hundred sheets of 8x10 HRT-Green cost me about $45US shipped to my door from an ePrey vendor. I'd far rather play around at less than $0.50 a shot than four or five dollars per. It's really that simple!
(If I ever get past the current crush of yard work, I may yet get some hard evidence! )
