I got a couple of keepers after all. I finally got around to trying out a roll of Kodak's pro slide film - E100VC to be exact. That "VC" means "vivid color" I believe, and I'm guessing it's intended to compete with Velvia 100. This being my first roll, the jury's still out, but I think it's got a broad range for sure. Sometime soon I'll try me some Kodachrome :-)
