i go with "drops"!
1) find a "swanstem" gooseneck stem (search eBay)
2) add to this a "randonnierre" set of handlebars. (")
3) apply "grab-on" padding (lbs) and you have the best handlebar ergonomic means, that i have yet to find, way to ride!
also, with a drop handlebar, you have more options of hand position too, like Modernjess stated above.
good luck in finding the classics listed...and the choices you make in your handlebar!
