Height doesn't it really matter much, your weight matters more for size.
The dark series is a great board, but it seems like the salesman is trying to up sell you. If you haven't been snowboarding in a while you don't really need the dark series, its an expensive board made for charging the mountain. There are many wide boards that might suit you better that are also cheaper.
Give us your weight and what type of riding you do and we can recommend a few boards.
