If you really really want to heli fish just go to Bella Coola in BC Canada.
WAY cheaper.
Also if you ski, go to AK and fly with the Chugach Powder Guides (Owens who's one of the guys there is a riot) and do Kings & Corn.
"Spring" AK heli skiing, white water rafting, and king salmon fishing all in one trip. All inclusive for a week is like $8000
