i agree tah the ghettos are really nice skis, but so far, i haven't heard a single bad comment about the dumonts.
to tell you the truth, i think this is personal preferance between these skis.
if you want a medium soft ski, get the dumonts
if you want a stiffer ski, get the ghettos
if you want a more mellow sidecut, but a similar flex to the dumonts, get the ar6. i actually was going to get ar6s but i decided i wanted something with a bit more sidecut, so i got dumonts.
these are all sick skis and im sure you'll be happy with any of them, i think you should just find out what you are looking for in a ski and make a decision based on that, plus a little input from ns.
