Rear only. Front is V-brake, although there are posts for rear V-brakes, too.
Judging from your post, perhaps our rear disc is optimized and I'm expecting too much of it. For some reason, I though a disk should brake better than a V, but I've never had disc brakes before.
I do use the front brake for the big share of braking and am happy with the V up there.
Maybe I'll add V-brakes to the back and give the stoker the lever. That would make her happy when I'm getting too enthusiastic for her downhill!
