I started out like you, loath to give up my bombproof Everest-quality Gregory Snow Creek, the pack I carried up and down many mountains, glaciers, volcanoes, etc. I loved that pack, but it weighed almost six pounds!
Finally I realized I just had to go "cold turkey" and replace it with a modern, lightweight pack. I'll admit it was difficult to do this, but once I got past this big step it was much easier to replace other old, heavy stuff with lightweight equipment.
One thing that helped was eBay...it is fairly easy to get perfectly good used equipment for way less than list price.
So my advice, Bill, is to bite the bullet and give up your old pack, as difficult as that seems new. You can easily shed over five pounds this way!
I recommend a Golite Jam or Pinnacle as a replacement, if you can get your total loads down to their comfort range, but there are many other perfectly good alternatives.
