The thing is that Traceur is actualy misspelling anyways, the oreginal name of the David Belles second team was les tracers with tracers being borrowed straight from english. Their is no strong logic behind have different terms is just a matter of preference. Stephane vigroux has indicated he finds it odd and limiting that the community has adopted what was orginal a team name, we don't all call ourselves Yamakasi. The names only matter so far as how effectively the communicate if you ask me. If everyone calls female parkour practioners traceuse thats fine with me.
