Interesting. On my flat bar roadie I switched out the turkey wing equipped drops and stem mounted friction shifters to flat bars and Shimano indexed pods with brake levers. They are for v brakes and I'm running single pivot calipers on the front and dual on the back. Interestingly the single pivots feel and work fine with the long pull levers. I think its something to do with the fact that they are cheap and the springs hold them way out. The rear dual pivot I installed actually does work.. it feels a bit wooden but you can lock the rear wheel without too much difficulty. Not as nice a feel as the v brakes on one of my other bikes but almost as good. It did take a bit of tweaking with the cable length and shimano 105 pads to get it to work though.
