@John With all this nice weather, any chance you might be bring out the BIG guns this weekend? You've already got a volunteer Sherpa for most of the 7x17 gear should you decide to use it.
P.S. Have you tried 7x17 x-ray film yet? I'll be bringing some x-ray film samples, it's pretty good stuff, and the price for 100 sheets is what you'd pay for ~3 of a brand name emulsion.
