Check on evo.com, they have a size chart for each individual board. The 156 shows 125-175 lbs, while the 159 is 145-195. seems like you may find the 159 a better fit?
The size chart on Evo is junk - it is not from NS, just something the Evo sales guys drew up.
The guy should be on the 156 for sure, unless he is still gaining weight and/or planning on riding a lot of powder.
