After a LOT of online searching searching this winter, I pulled the trigger a pair of Nordica Steadfasts to make my entre into the NTN world. They made their first voyage Superbowl weekend and have about 10 days on them total. The ski is terrific, I only wished I bought it in 170cm vs. 178. They have almost an identical sidecut as my Saloman Pocket Rockets which I love. Probably akin to a Molkl Mantra by Today's standards. I would say that 6'.0" and/or 175 lbs is the starting height/weight for this ski, as it is stiffer than I anticipated. I am 5'10" and 160lbs and still ski it fine, I can just tell it's longer than I would ideally want. In any event, before the season is over I am listing them here for $350 with a Rotafella 2nd ski kit included. I will be up at Gore next weekend and the weekend thereafter so if you want to check them out, shoot me an email.
