Alright Gary,
You want to save some weight.
Well I can be very blunt on how to.
First of all, you are failing in the warmth category.
You have all of this to keep you warm:
Tachyon Hoody/ or Z-pack rain jacket
Pat-Cap 4 bottoms
Pat-Cap 4 top
Houdini Pants
Down Booties
Down Hat
Gloves
MB EX-lite Jacket
So you have the gear and are dressing for 15 degree weather but using it for 35.
This means that one or two things is wrong.
So you have a 30 degree quilt but it doesn't keep you warm without the 37 ounces of extra (base weight) clothing from above.
That doesn't even include the clothing you are hiking with.
The real problem is the jacket.
You need a warm enough hooded jacket so you can ditch the Cap-4, gloves, and down cap.
So an extra 3 ounces in a warmer jacket could take off 10 ounces, saving you 7 ounces off your base weight.
Next up is your tarp and bivy.
It seems you need a bivy because you don't have enough coverage with your tarp?
Why both? Maybe you should have bought the Solo Plus for 1 more ounce.
Then you could have saved 3.75 ounces leaving the bivy at home.
The same goes with the sit pad and pillow.
Why not use something that could work as both?
Last – You have "Now total luxury XUL (SUL) is possible"
Are you implying that you want to try to go XUL?
Because you are nowhere close to XUL.
Not sure why you would even hint or throw around the XUL term.?
If you really want some areas to drop weight, you need to reconsider your "luxuries".
Most are not "luxuries". They are not even necessary, just redundant.
This list looks like someone that has no skill what so ever that is going to try to be SUL at a campsite.
Most people who work at getting their weight down are not camping at campgrounds.
Without the campground factor, you can now be free to find a camp site that has soft ground.
With soft ground, you don't need a full length air pad. Soft ground is softer than an 11 ounce air pad any day.
So to me, this list just lacks one big thing; Experience…
