i have a 09 XAM 2 and im in love with it. handles great through fast stuff. im a crappy climber, but it feels about the same as my old enduro. dont really notice the weight, but the xam1 is probably lighter than my xam2 anyway (im around 33lbs). i ride mostly ugly rocky trails with steppy climbs and steep descents. if i was riding smooth trails i might think about a different bike.
