im sorry but they are the same ski, they were gonna be one, but for marketing reasons they made two topsheets one, (the nobis) was originally for canada only and the super nobis was gonna be the all around big mountain stick, but for fear that the mass population would not like the lbf they made a second topsheet for it, and moved the mounting back a little,
oh yea the inspired does have a twin! its the same as the lbf and as the concept! no dynastar has every had a big twin tip, you should know that by now,
and why dont you tell me some of the differences in the 'construction' of the skis
