Replying to Motherships/Length

I've decided to get Motherships this year for big mountain skiing and backcountry jibbing but I can't decide if I want to get the 182's or the 192's. I already have Skogens for the park but I would like to be able to use my Motherships for the park if I had to as well. I am afraid if I get the 192's they will be too long for the park and even somewhat cumbersome for backcountry hucking. By the way I am about 6'1'. Any thoughts would be greatly appreciated.
