Disclaimer: I am sure there are much bigger experts here then me. I tried a frontier 158W and it did not feel wide to my small (size 8.5) feet I would go bigger. Remember that the waist is not the only factor your boot is actually further back and the width differential is slightly larger there.
PS are you sure you want this board? Its good, I am sure you will have a good time but someone light with really large feet (like yourself) is much suited to short and fat then anything else really.
