i'd say if your gonna ski park only it's about preference. i used to own 167 chronics and they were a great for park really manouverable (i'm 5'8). this last season i stepped it up to 177 chronic wides (more my size) and they absolutely owned... specially for my type of riding 40%park 60%allmtn. so yeah, it all depends on preference and what you are gonna ride.
