Glad to hat I found this thread and that there's lots of like-minded people on here
I love those BMCs.
As for the disc CD rim brakes debate I went to discs last year on my Roubaix and I have a Roubaix without discs and the same spec (other than some upgraded Mavic wheels) and all I can say is that the difference is challenging and cheese. I can safely say that I will never have another road bike without discs!
