I think that in the 1980's (which is when my kids got old enough that I could go out without them, and my non-backpacking husband and I separated), there was a big emphasis on heavy gear and taking everything including the kitchen sink. It worked out just fine until I tore nearly every ligament in one knee on an X-C ski trip. Now, of course, at 78 (you're still just a spring chicken, Jim!), it is either use lightweight gear or don't go at all. However, I am basically out of the gear purchase mode because I'm happy with nearly everything I have!
