So it's like Sophy's on steroids?
Verrrry interesting. I would have guessed that the smell would be the clincher, but I have experience with the same cultivar smelling different in different parts of my garden... There is a definite olive green caste to the foliage of your mystery rose that might distinguish it; does your Sophy's rose have that, too?
Maybe Toni is right, SJB appears to be a little orangish near the center, too.
