I've been using this setup for 1700 km (and a good chunk of them in the dark too) and so far so good. I might go back to a b+m secula anyway because not having a rear light when stopped is a bit of a pain.
Have you done any side by side comparasion with a supernova that is connected to a supernova front light? i.e do you think it's less bright, or just no standlight?
I actually asked about that on the previous page :)
