not always true. however, there is truth to this. when your going to be starting out, learning tele turns and just skiing will be nicer on a softer pair of skis. but if you start to get good at it and start charging, youll most definitly want a stiff pair of skis, just like regular skiing.
for instance, i started on a pair of 179 pistols, and they were awesome for about the first year, but i got good fast, and the last several months id been using a pair of ANTs mounted tele at like -6 i think. totally awesome. so start softer and probably shorter, and if you feel like your going to get better,faster,etc, try a pair of longer, stiffer skis.any other questions pm me.
