The aura is pain in the ass for east coast skiers skiing true BC runs.
Not enough float and to stiff, me and epic have friend that sadly we are saying told you so to her Aura purchase.
To the OP you want a ski about 100 underfoot, with some camber for skinning, but at least tip rocker if not tail rocker as well. If she plans to just tour on them mount with dynafits, if she wants to ski resort days on them get the Marker Tour10.
Some thoughts on skis
156cm or 163cm Blizzard Crush - amazing versatile ski, alittle heavy, can be mounted for alpine and at and tele using different plates. can be had pretty cheap if someone has a PSIA hookup
163cm Volkl Bridge - lighter than the crush, might even be better in trees than the crush, the Volkl ELP rocker profile doesnt skin uphills as nicely as the crush camber profile
162cm Volkl Kiku - lightish, best tree ski I am mentioning here, probably not as much fun in corn as the narrow skis. volkl rocker profile doesnt skin well but it sure does ski nice.
156cm Icelandtic Nomad SFT - light and the strongest most durable ski mentioned. Only non rockered ski that really works well for EC BC skiing.
155cm Icelandtic Oracle - light tip rocker and even ligher construction than the Nomad could be a good thing.
whether you listen to me or not I know I am right. Skinny stiffer ski with no rocker have no place in the east coast BC.
