Replying to 1080s vs. Pocket Rockets

I bought a pair of 1080s of a friend for a great price last summer, but have come to find that my fears have come true. They are too short. I am 6'0 190, and the skis are 167s. They dont cut it in the pow. Other than that they are really fun. I think I am going to sell them to my sister for a good price, they will work great for her. Well, here is my delema. I cant decide if I want to get 181cm 1080s or 185cm Pocket Rockets. They both have so much to offer, I am just stumped. I am trying to progress in the park area, so the 1080s would be best there. I dont really spend much time in the back country, I just want a great ski for pow. The Pocket Rockets seem like they would be best for that. I have read reviews that say the 1080s are a great top shelf ski that do well in all areas. So what should I get. I know the Pocket Rockets carve very well, and that is something I really love doing. Do the 1080s carve well? Please help me, I am very serious about this. Any advise would be appreciated.
