To each their own I say. My daughter has been ice fishing with me since she was 6. I mainly ice fish saginaw bay, which tends to be as volatile and unpredictable as lake erie. She only goes on a few trips a year, and its well after I feel comfortable being on it myself. In my opinion you are doing everything you can possibly do to mitigate hazards. Most people are lucky if they are taking 1 of the items you mentioned on the ice. I, like you, am prepared for the apocalypse when I venture on to the big water. There is no such thing as being too safe. You are more than prepared, always venture with caution and confidence and it will usually keep you in a "safe" position. :-)
