From my understanding you’d want the (cable) disc as the drag. Our thorn also only has V and they’re good when well set up with good cables and proper brake pads .
This makes sense to me too, but on our Santana the rear V was the drag, and the disc was the regular brake. Built like that by JD Tandems, don't know why.
