I started this project a couple weeks ago, http://www.backpackinglight.com/cgi-bin/backpackinglight/forums/thread_display.html?forum_thread_id=63863
Since then my Z-packs and DIY Gear Supply orders arrived. Ive removed all that will be removed and the re-constuction is on going. Im replacing the front panel and extension collar with taller lighter (1.1 oz sil) ones and adding a front mesh pocket. I also replaced the huge 1 1/2 hip belt and laughably small hip belt pockets with a removable 3/4 inch hip belt.
The weight is coming in at 10.1 ounces, though I expect to add roughly another 3 oz before Im done. The pack weighed 24 oz when I started.
