custom vs white collection

i want to know what is the major difference between burton custom board
and whtie collection(adult).
from the spc. the data almost are the same.
the only thing i know. custom is all mountain board
white collection is freestyle board.
can someone help me out and give more info about whtie collection board?

Custom isn't a twin this year, its a twinish shape, but still a directional core.  The nose is longer than the tail by about 10 millimeters or so, kinda like the Roma Agent which is also mistakingly called a twin quite often, even though its not really.  It also has a much faster base and is slightly wider.
