Replying to How tall are you and how long are your skis?

So I'm looking to get my first pair of park skis soon and I have no idea what length to get. I'm always hearing that shorter is better but all the reccomendations I've been given seem too short. All my friends are 5'4 and under and they ride a 151-55 but thats wayyyyy too small for me. I'm 5'6 and I was thinking of getting on a 165-67. Is that too long? Too short?
I've also kinda lost touch with appropriate ski lengths because FIS has all of us racers on super duper short slalom skis and uber long GS skis. If you could reply with your height and prefered ski length that'd b gr8.

Oh and also what brand of pants you like. I need pants.
