Replying to Line step ups too long for me?

Hey guys, new here. Found some line step ups and want to buy them since they are dirt cheap on evo and I just want a dedicated park ski for when I'm just in my back yard, rabbit hill (Edmonton), or on shitty snow days in the mountains when I'll be doing 80% park (I have another pair of skis for pow and crud and charging). My question is are the 184cm size gonna be too big for me. I do probably 50/50 rails and jumps and 6'1" 160lbs. I don't know if it helps but I am an advanced skier and am getting more and more into park
