I'm not going to post a bunch of photos.
I ride kirkwood a ton! over 100 days in the last 2 seasons alone.
At 160lbs a 162cm should not be too big for you if you are in shape and are an advanced/expert rider. I am 155lbs and have a 161cm board.
Now back to the debate at large.
If you are looking for more of a freestyle fun package I will suggest the following powder 'freestyle' boards.
Yes - Pick your line
K2 - Ultra Dream
Burton - Barracuda
Jones - Mountain Twin (arguably)
Since you want to spin and have more control I would size down to a 158 or so but I'll be honest. That 4cm is going to make that much difference in turning in powder/trees.
Just my 2 cents. Take it or leave it. I don't care.
See you at kirkwood
I'm up Wed through Sun next week.
