I carry:

-Penny Alcohol Stove
-Snowpeak 600 ml single wall titanium mug
-Aluminum windscreen that I stole (and cut down) from my old Whisperlite
-Lighter -- I actually carry several. One in my bear canister, one in my cook kit, one in my sleeping bag stuff sack, and one in my clothes stuff sack. It ensures that I'm never without fire. Been on the wrong side of that one and it sucks.
-Titanium spork
-Plastic folding cup

I don't have the exact weights, but it's more than two pounds lighter than what I used to carry.
