Do it now, go for one day. You WILL have the best day of your life and you WILL become addicted. It's the way heliskiing works, you do it once and it's the most addicting drug in the world. Great stuff, I'm heading out for 2 or 3 heli trips this year in Panorama at RK Heli-skiing. Went twice last year, one day of pillow lines and neck deep powder, one day on the alpine glaciers huckin cliffs and such.
