Need some help

Ok so here is my story. I skied for 5 years from 6-11 then switched to snowboarding. This season i have been teaching lessons and using the shops skis. Im now wanting to buy my own and need some help on what to buy. I dont know much about skis anymore since the tech has progressed by alot. im 5'11 and 240 lbs im a big guy my boot size is 11.5 but i have wide feet so i use 12.5. So ive been doing a little bit of freestyle and i enjoy buttering and being able to do spins and such along with a few rails tossed into the bunch. So probly a freestyle ski that will be able to handle the notorius back country of alaska. Thanks guys if possible a full setup if you feel like spending the time to help out a fellow rider.
