The problem with the VO Left Bank and Monmarte bars is that they're out of stock. The bars on the Super Course look like Nitto Promenade bars. I plan on putting Promenade or Monmarte/Left Bank bars on my wife's mixte once I find another frame. I've never used bar-end brake levers, but I imagine that city levers have a better pull and would feel more natural. I could be way off base here. Also, I don't care for the asthetics of bar-end brakes. FWIW, my wife had VO Porteur bars and Guidonnet levers on here last mixte (frame was too small). She liked the bar shape, but I was less than impressed with the efficiency of the levers. Sure looked good, though!

My advice on the stem is first figure out what reach you need and how high you need it. Then you scour eBay for a used Nitto or even a Raleigh-branded or SR stem. They're fine stems and look great after a good polishing.
