I'm 5'11 and weigh 160 on average, but usually have to cut down to about 150-155 during the winter season because of another sport, I wear a size 11 Burton boot, I have read a few other questions and said that the sizing goes down by one, so if I have an 11, it will actually be a 10 (for the Forum Republic bindings) What size of snowboard would I generally need for mostly groomed park time, and a bit of fresh pow. And would I need the Wide?
