A lot of good information here and I think I will try some Velvia as well as some others discussed here. I have been exclusively using E100G and E100VS. I really like the VS for low [and warm] light.
I should point out that Ilfochrome/Cibachrome IS STILL AVAILABLE both at a number of labs as well as the materials to print in one's own darkroom. I have used The Lab and the work is profoundly excellent. I encourage everyone to avail themselves of this process: it will keep it alive and you will never get better color prints! See the below links...
