hey im 6'1", 160 and im buying a ski for mostly park but also farting around the rest of the mountain when there isnt a lot of snow. is the 178cm too short? i think its the longest size so does it measure shorter than it actually is?
He won't need that big. He is only 160lbs. Weight is usually much more important then height in ski size selection. The 178 should be ok so long as you are good with a really soft ski. If you are worried about stability look for something of a similar size or up to 181 but in a stiffer ski.
