Just got a beauty of a ski in the icelantic nomad, 168, 140/105/130, with tyrolia railflex 14s. i live in the NE amongst the hard pack and groomer slopes waaaaa. i'll make a few trips out west to tahoe, CO and utah but how will these babies do in the hard pack up here in the gloomy NE??? i ski the trees and try to find a little fluff in closed lines but if i get slapped by patrol how will i fare on the groomers???
