I think it would look more legit on a long rail that was open underneath.  Not saying it doesn't look sick now, but the first time I saw the TC Mt Hood edit and I saw Andy put his ski under the rail and use the center support to help him BS SW UP, my jaw hit the floor.  I'm sure he could pull the Gypsy Killer on a similar rail and use the center support for a FS SW UP.  That would be ill.
