I like the idea of having the airbag. When I got my first avalung (before they made the packs), it worried my family and some friends that it would make me ski scary avy terrain. It didnt. I am still OCD and uptight about being safe, even more now that I have a wife and a little baby depending on me. I think the airbag would just make me that more comfortable. All equipment has its limits, the most important part of being safe is leaving your testosterone in the truck to help you make better decisions (yes this is aimed at us boys, we are more dangerous).
Please be safe!
