Opinions on an AT thru set-up

[SGT Rock]

Here is what I have already set up for my thru-hike, January 27 start date.

For the base:
HH Hyperlite with snakeskins. I have added a couple of carabieneers for a little faster set up. 22.22 oz
HH Stock tarp with JRB slingshot tie outs - 9.33 oz
A 1/2" Oware pad with a mummy cut - 9.72 oz
2 MSR needle stakes - 0.64 oz total
And a Hungry Howie down quilt - 18.02 oz
Stuff sack for the quilt - 0.78 oz
Total = 59.71 oz or 3.73 pounds

With this sort of rig I am comfortable into the 40s and can make it to the 30s.

To take me down a little lower:
JRB No-Sniveler Under Quilt - 21.27 oz
JRB suspension system - 1.13 oz
Total = 22.40 oz or 1.4 pounds

With this added on I am comfy into the 30s and can make it into the 10s or 20s.

Then for the really bad weather I also have this stuff for a back so I can shield the system or go to ground:
JRB Weathershield top and bottom - 14.49 oz
JRB Stuff sack - 0.46 oz
Emergency blanket "groundcloth" - 0.88 oz
Total = 15.83 oz - almost a pound.

When I start I will have all this stuff in addition to all my clothing. The whole hammock kit is 98.94 oz or 6.2 pounds

My experience with this layering system is I can be comfy down in the 20s and make it down to the single digits while still hanging. As I proceed north and the weather improves, I can send home stuff I do not need.
