Good to know! I actually bought a Chicago Hardy from Hirts a few years back. It is crazy tough. I grew it outdoors in northern Vermont (zone 3/4), overwintering it by piling lots of leaves and straw on top. I dug it up, potted it, and brought it with me when I moved...but was hoping to find a suitable companion.
I hadn't heard of the Olympian Fig. That looks great!
