Replying to Good old new skis and size question

The time has come to get some new skis. I am 6ft 200 pounds and a pretty aggressive skier not the best on the mountain but I can hang. Unfortunately I live in the midwest put get a few good trips a year out west. I prefer powder,cliffs,trees over the park probably 75/25 is what I ski. I have spent the last 3 years on the original 165 pocket rockets. yeah I know way short, they were a gift.

I'm looking now at the Scratch, Seth, Gun, Prophet 100, ARV's, and the 4FRNT VCT. I know that is a big list but I'm not for sure what would be the best for me. I know these have all been talked about a lot but your advise would be a big help.

The other issue is size. Should I go with the bigger ones like around 180 and up? I have never skied anything bigger then a 175. Thanks for your input guys.
