The first thing that pops out to me about your gear list are all of the cutting devices.
Razor Blade .125 oz
Swiss Army Scissors .25oz
Leatherman Squirt P4 2oz
SOG Seal Pup Elite 9oz
SOG Flash 1 1.3oz
That is 10.675 ounces of cutting devices. Do you really need all that? It seems overly redundant. I carry a 0.6 ounce Spyderco Ladybug and it is more than enough knife for anything I have ever needed it for. If you really wanted to cut the weight, you could just carry the Razor Blade and Swiss Army Scissors.
I would ditch the ground sheet. The Contrails sil floor should hold up fine as long as you are careful where you pitch it. Painters’ plastic doesn’t provide much protection anyways.
The mug you have is quite light, and I see you like coffee and tea, but I would suggest just drinking out of your cookpot. You should at least try it on a trip or two; I bet you don’t miss the mug.
Speaking of the cookpot, is there any reason why you need a pot that large. If it is just for solo use, I use a 600ml Evernew pot that only weighs 3.4oz. Six ounces is a lot for a solo cookpot.
If the Smartwool baselayers are for sleeping and camp, I suggest using polyester or silk. I love to hike in wool in cooler weather, but even in the winter use Capaline for my sleeping clothes because it is so much lighter. Wool is just too heavy to carry.
You could lighten your beanie a bit if you really wanted. My Mountain Hardwear Micro Dome (100wt fleece) is just over a ounce.
Your First Aid kit seems rather heavy, but I have to say is one of the most complete kits I have ever seen without having a bunch of useless items. My only suggestion might be to lower the quantities of some of the items.
There are a few things you could get rid of in your gear repair kit. First off do you need the floss if you already have a needle and thread? What about the Velcro? Could you not tape anything instead of using Velcro? You could probably even patch your NeoAir with the Tenacious Tape if need. I would also ditch the Specra line and “borrow” some of my bear bag line if I was in a emergency and needed it.
In the utility and survival section I would get rid of the spare battery of the Ion. I would also get rid of the Carabineer (you already have one with your bear bag kit), the compass (you already have another compass and a GPS), and pen (you already have a pencil.
As for your luxury items, I know you don’t want to give any of them up but, do you need the iPod and the Radio? Also what is the Monocular for? And, I know some people like them, and depending on the type of hiking you do, it may be a great asset, but I would consider dumping the GPS and just use a map and compass.
That steak dinner sure does sound good, but it is terribly heavy. I am not saying you should give it up, but that is a lot of weight for one meal. Your camera also weighs a ton, but I realize that there are limitations to what my little 5.5oz camera can do, particularly in the hands of someone that knows what they are doing (in photography, that counts me out.). I have just always thought that hiking with a large DSLR and associated lenses would be awkward.
