Need help finding a park board (snowboard)?

Im 6'4" and have been snowboarding and riding all mountain for 13 years, since I was 5 and I really wanna start getting into park. Currently I ride a 167 Burton Baron and I love it. I want to get a park board to kick start my new interest but there is one problem. I can;t find one wide enough. I have a size 15 boot and I was looking at some 155's and sizes around there. The waist sizes of those boards though are tiny.... like 24-25. Does anyone have any suggestions on a good board that would maybe fit me better because of my big *** feet?
