And a follow up comment, who really needs a high end full suspension Fat tire bike !!! I have ridden no suspension fatbikes and they are great! ( Next we will be seeing Red Bull Rampage on fate tire bikes)

I voted for weight as most important only because after many years & many bike models through the decades that I've ridden weight is a factor, geometry would be number 2 on the list but I have found that this day & ago most bike makers get the geometry pretty good on the first try!!!
