i would like both. I prefer braze on shifters but if you wanted to go fixed, [protecting face from inevitable blows and calls of blasphemy and heathen], it is nice to not have the braze on.. also i think routing the cable below the top tube looks better and with braze ons you have no choice but to go on the top unless you put clamps on and then have ugly braze ons left anyway unless you want to cut them off.. but that is a lot of work.
