The length should be fine if you want them as an all mountain ski. If you are only going to be using them in park, maybe a little shorter? Not sure, I don't ski park. It also depends on your skiing style. If you ski tight trees and bumps a lot you're better off with ~180 but if you like going fast, charging hard, cliffs and pow fields, then the 188s would be a perfect length. I'll leave park-specific recommendations to others.
