Great reply AK NIMROD! First of all, I pray that I can still do what you do at 60 years old! I hate to say it, but the only way I have been able to cut my pack weight down is to spend more money on "quality" gear. i.e. gortex clothing, sleeping bags, tents, etc. The bulkiest items in my pack is definately my clothes. I need to find multi-purpose clothing for all the elements, yet being really quiet. I have been looking at Sitka gear for its durability and quality, but I dont know if it is worth the price.
All in all, if what you have in your bag works for you then stick with it! It is just a matter of how your knees are going to hold up! If you have any questions about how to lighten your load, then please leave a post!
