Even tho I like the Paul Racers for a bunch of reasons, the Mafac Racer is my favorite classic CP. I like the Racer because you can make your own cross cables AND because you can install the Compass brass bushings which are a significant improvement over the now 40 year old plastic bushings. Roller straddles are cool too, if they appeal to you.
I don't trust old school cross wires. If one of those pops, you are down to one brake. It will let go at the worst possible moment.
Of course, use new pads of your choice, the best wires and housing you can find, properly rigged, and if possible the Weinmann levers which are the best, again IMHO.
