Im about the same dimensions as you are (6', 165lbs) and I ride a 154W. If you ride mainly park, then maybe the 153 would be better suited. But I like getting the shortest deck I can ride because Im mainly in the park. But my Rome Machine takes me everywhere. So if you do ride more than just park, then def get the 155 as it will help you to perform better all over, rather than the 153. But either one and ur good to go bro. Hope this helped
