Sounds like you just finished at OU--I got an MFA there back in 2001, hiked Zaleski a few times. Wish I had done it with a lighter pack.
Overall, nice list. Might be time for a new pack, better suited to the weight of the rest of your gear and your typical trip length.
You could save *maybe* 5 oz going with EE's lightest 30* quilt, and they have just about the best combination of lightweight, quality, and cost. If you can sell the RevX, maybe it's worth it. But I'd look at pad, pack and shelter first.
Does the Duomid really weigh 29 oz? I though it was lighter.
I didn't realize the Zlite was 14 oz--given the r-value and (reputed) low level of comfort, you might want to try something else.
Not quite sure why you have a dirty water bag when you use Aqua Mira--what's your procedure?
+1 on Ben's suggestion for the polycro/window film groundsheet above. Mine is trimmed fairly small--1.5 oz. Amazingly durable, given how thin and light it is.
