I've been riding the custom since Saturday, awesome looking board.
It has a snowboard base so scratches can be smoothed out with an iron.
Coming from a caliber it does require you to be powered to ride, but through large chop I struggle to nose dive it. I found landing very smooth in comparison to the caliber, although the board is extremely stiff under your feet it's quite nice to ride, going upwind requires you to really dig in both heals.
Pop took me a bit to get right but now I find it easier to get huge height more repeatedly even in miss matched chop. The board also feels really light in the air and is easy to swing around, no over rotations and uncoordinated raleys due to swinging heavy board.
I've never really had any time on the previous custom so I can't say if it's worth upgrading.
