never a…

hi all… im 175cm tall 83kg and take a us 12 boot…i want a all mountain board ie burton joystick v rocker but am unsure between the 156w and the 159w ,ive tried some calculators and they vary between 155 and 162 in the lenght recommendations so really need help..i obviously need a wide because got big feet but the length i thought 159 would be too long for my height but right for my weight
