As a splitboarder myself I think that for many (not all) tours the board is very practical and a fun way to cruise the mountain.
I mean splits do have their down sides, they don't edge as well, so steep traverses can be difficult. Also, rolling terrain is kind of icky unless you are proficient at skiing in split mode.
One of the largest split manufacturers is based in Whistler, Prior, yep,yep,yep. So, it mustn't be all that bad
