It's not just that. I really feel that old Mantras/Auras, which were really popular for a lot of wrong reasons, were really good skis for the right person, and Aura in particular filled a niche that no one else cared to serve. MX88 is an amazing ski and is certainly worth its price, (even if the cost per centimeter becomes even higher in 158 size .Does come short enough....158 for the MX88. But there are few more loyal out there to Aura/Mantra lovers especially if they ski at Squaw, to try to convince them that anything less than 98mm is acceptable it very tough..near impossible.
But nominally there is nothing else to replace the old Auras. Even to this day its practically a required piece of gear for a strong charging female skier at Squaw. I actually starting to believe that Blizzard missed some opportunity there by not making a metal Samba. Of course this is a small group and, being at Squaw, highly skewed, so I am sure the Blizzard MBAs crunched the numbers and decided it was not worth it.
