I agree. If you use the stuff, it's worth it! After all, what else are you going to do with the money? But there are a few items on your list that I don't carry:

teva sandals................................22--I use crocs, which weigh half as much. And I have a pair with bungie fasteners to keep them on when my fishing requires wading.

weather blanket/ground cloth...........12--I use a poly tarp--again, about half the weight.

Sea to Summit 10L carry water basin.....5--I don't need this. water bottles work fine.

Integral Designs poncho/tarp..........10
Golite Tumalo rain jacket.............9
REI UL rain pants.........................13--that's a lot of raingear. Admittedly, YMMV, but I just take the poncho.

2 spray cans (powder) Off repellent...8--we use non-aerosols--they weigh less--about 2 ounces each. Remember to count the weight of the containter, not just the contents.

flashlight/lantern combo..............6
Petzl Tikka XP head lamp..............4--do you need both? We don't.

Those changes would reduce your pack weight by about four pounds. Not a huge deal, but importnant none the less--at least if you are going to the trouble of leaving the cardboard tube of the TP behind!
