Christopher, here is my shot at your list (with my bias):
MSR Miniworks 17.8> way to heavy, use chemicals, steripen, or gravity filter, you will save 14 oz minimum
water carring bag 2.1> redundant you have 3 platy bottles
MSR Whisper Stove 11> light options available- use alcohol or canister
1L platypus 0.9> make one of these a 2 lt for little weight penelty, you don't have to fill it all the way and it gives you more options
MH pathlight3 Tent 33> I think this thing wieghs 5 lbs 12 ozs., you can shave a bunch here, at least 3 or more lbs. A tarp or something like a DBL Rainbow Tarp tent for example…
A's Pillow 5.3> personal choice
first aid 8.5> this can be around 2-3 oz., knowledge is key here
toiletries 4.7> what is included here?
fuel 13.3> see stove above
C's waterbottle 6.5> 6.5? (please not the old nalgene!) you already have 3 Platy's- use a old Gaterade bottle at 1.3 oz.
Sleeping bags 83> this is 2.5 lbs a piece, there are much lighter options out there. When you can afford it, this is one area to save weight that will pay off.
A's pack 70> 4+ lbs- loose half that. You can get a 1 lb 12 oz Golite Jam 50 lt for $64 at their website right now
C's pack 72> 4+ lbs- loose half that. You can get a 1 lb 12 oz Golite Jam 50 lt for $64 at their website right now
A's glass cleaner 1.5> explain?
Wash tub 3> are you bringing an infant who needs a daily bath? use your cook pot or just a wet bandana
The rest of the stuff on the list is ancillary to fixing the above first. I hope this helps and helps to plan for the future.
Tad
