what kind of riding do you plan on doing

I'm going to be all over the mountain but
mostly the park

I would get a 151 or 152. The reason being is that if your not purely into park riding, meaning you wanna go all mountain, your going to need a bigger board. The only problem is your weight vs boot size. You got a very big foot for your weight. I have the same problem. Im 5 6 120 and have size 11 boot. I ride a 150 and it fits me just fine. I ride the park pickle though. These boards are very similar. I would go with that for now. You should grow into it but 1 or 2 cm wont affect you greatly

yo billy...For park riding size down and for pow size up...im going to assume you've never bought a board before...your 5/4 so i think the smallest size that they offer....also you might want to take a quick look at the sizing chart DF offers
