I'm a buyer for a shop and I've had the chance to ride everything out there. There are a few boards that stick out from the rest which I'll share with you. Based on your height and weight I would normaly recommend a 159-161 leangth. 164 seems a bit long unless you're riding the steep and deep.
Lib Tech TRS/skunkape. Skunkape is the wide version of the TRS. Either board is the best all around board out there in my opinion
Rossignol Angus (killer snowboard for the price)
K2 Turbo Dream
Lib Tech Dark Series (if you want to spend the big bucks this board is beyond solid, it's what I've been riding this season)
And if you wait until next season, the Ride Highlife is going to kill it.
