Mike,
I used the Woodland Scenics stuff. It wasn't the uber fine stuff, but the size just a little bigger than that (I think it's the mixed medium grey). It makes for excellent O scale ballast, I think. The finest stuff they make is excellent for gravel for parking lots and gravel driveways, I think.
BTW, thanks for the kind words, and your layout is really coming along!
