Wow. You are quite adventurous. I love experimenting but you certainly are the pioneer. I still need to venture out into using my new camera but I went out this morning and took pictures with my phone of the roses that are super winter hardy. I don't do any winter protection even though every year I say that I will. The only winter protection that I do is move the ones that grow in pots to the garage. Here is a list of my most winter hardy roses based on this year's brutal winter:

Hansa

Therese Bugnet

Purple Rain (this little rose is a tough. She had no winter damage whatsoever and was the first to show buds)

Break O'Day (hard to find but well worth it HT. No winter damage either)

Sharifa Asma (always reliable)

Celsiana (I think she must have spent the winter in Florida b/c she did not have any winter damage and has the most flower buds that she has ever had)

The Fairy.

Here is a picture of Purple Rain which I got as a gallon plant last spring from Chamblees. It is loaded with buds.
