I get so little time to shoot anything that I sometimes lean towards the "spray and pray" when I do get out. But I still try to make it worth using, not so much for $$, but for my editing time. I get irked when I have a whole sheet of negs and nothing worth printing. With 35mm, I might need to let it go even more. I barely shoot 10 rolls a year of 35mm. Probably 20 of 120 and maybe 50 sheets of 4x5 a year. Though likely less out here.
