I've got a 83 LeTour with "safety levers". It came with them, and they are fine for low speed stops. I do keep the adjustments pretty tight, loose they are not much good.
My wife insists on some kind of levers on the tops, so she has safety levers on a couple of bikes and cross levers on another.
I've added cross levers to another one of my bikes and they are a much better solution for bikes with aero lever cable routing.
83 LeTour,
