Of course! That's why I published it. So ...
I go by weight. The number of pieces doesn't matter imho.
The Jetboil PCS is too small to cook for the two of us, so you have to look at the Jetboil GCS. All weights in grams - sorry.
Jetboil stove: 208
Jetboil pot: 223
Pot base cover: 41 to protect the heat exchanger
Pot lid: 48 Jetboil one
Can stabiliser: 22
* But this does not include an adapter for the canister, without which the Jetboil is no use in France. The weight is below.
* The Jetboil system dies badly in really cold weather, up in the mountains, when the pressure in the canister drops. Lert the canister get cold, and it struggles. People have reported hand-holding the Jetboil to keep it going. Yeah, well...
* It only includes one pot, and I often use two pots when cooking for the two of us.
* You could replace the plastic Jetboil lid and save a few grams - true, but.
Rad shield: 10
MSR Titan pot: 125 with lid
MSR Titan kettle: 123 with lid
Could I take the Jetboil stabiliser instead of the bit of 3-ply? I tried this, but the crimp at the bottom of the canister varies slightly between brands. The Jetboil stabiliser fits the Jetboil canister; it does not fit some others.
Adapter for converting French CampinGaz canisters to screw-thread fitting: 39 g Needed for both systems.
It depends on how you do the sums, but a similar one-pot system of mine is about 335 grams. Even with two pots mine is still lighter. But my sytem can be used in very cold weather: you just take the radiation shield off the stove and let it heat the canister a bit. I have done this successfully in the snow. As long as the canister is just slightly warm to the touch all is wonderful. Not for beginners. You can't do this with the Jetboil - I tried.
The fabled Jetboil fuel effiency - yeah, well, it simply does not count AT ALL. We are resupplying regularly, and that includes buying fuel. A full canister (or a half-empty one) weighs the same, no matter which stove you use.
Sleeping bag stuff sacks: yes, a single stuff sack would be lighter than having the two sleeping bags packed separately. But Sue carries her SB, and I carry mine. And I decline to use my sleeping bag cover to carry water! Actually, there are two reasons why I decline: one is obvious, but the other is that I often get water from a little distance away for the evening *before* we camp. Bit hard to do this when the bag is still in my pack.
Helix Potty Trowel: this is NOT for use on ICE! Old spring neve maybe, but the stuff I am talking about is more like slightly consolidated corn snow. I know from previous trips that the Helix will have no trouble with it. No crampons, and light joggers! Frankly, I think the Helix could be overkill, but we have had neve on the passes before.
