I've switched to Delta 100 for everything seven years ago.
In 35mm it seems to have nice grain and work well.
In 5x7, it's tough to get but I have a box on the go.
In 4x10, I custom ordered 20 boxes from Ilford last fall and am enjoying the format and not having to cut 8x10 down.

I use it with ID-11 1:3
