Agree that the Heritage would be the best match in the NS line for the OP. Ideal size probably 155, but 158 not out of the question - but will be a lot more bomber and less playful.
Cobra could work as well. Softer flex than the Heritage (nominally the same as the SL, but in reality probably a bit stiffer), so less bomber/more playful. Also slightly better in heavy pow (not much difference in the dry, fluffy stuff like we have in Japan).
Sizing probably the same as the Heritage, but 158 would be a lot more manageable than for the Heritage.
For serious pow riding would probably have to be 158 for either board: I am 68kg/150lbs and occasionally struggle with the 155 Cobra where I am - really should be on the 158.
