Thom, no need to apologize. I was just intrigued by the contrast between the two posts. To show one of many alternatives, let me compare my gear to yours.
-Wiggys Sleep System-2 bag system (inner and outer) rated to 40F, carry weight 7lb 4oz
I have no experience with this sleep system but have read mixed reviews. I assume it is rated to -40°F, not 40°F. Do you know what each bag weighs and how they rate separately? When talking about sleep systems, your clothing should also be considered. I have a JacksRBetter No Sniveller quilt (1.4 lbs) that I use all year long. When it's cold I carry a Western Mountaineering Versalite Super (2.4 lbs) that is rated to 10°F. Combining the quilt and the Versalite probably gets me below -10°F. I'm not sure as I haven't pushed the lower limit yet. I've never needed to go to -40°F. My system is all down, which might not be recommended for wet environments. My clothing is wool and synthetic insulation to balance the down.
-Peak 1 Trekker Kit-4 piece dishes and spork 2lb 1oz
I use an Orikaso Bowl XL (1.4 oz) and a Light My Fire Spork (0.35 oz). If I'm cooking I carry a cheap Heineken beer can pot (1.23 oz) or a titanium pot (3 oz).
-Cabelas North Star Bivy-about 2lb
I sleep in a Hennessy Hammock (2.6 lbs). My Equinox Bivy weighs 6.5 oz but I don't often use it.
-CPF-90 GI Winter Pack-8.8 lbs
I use a GoLite Jam that weighs 1.32 lbs. I think it can be found on clearance for about $60. The less weight you carry the less pack you need. The Jam is very durable, has ice axe loops and good compression.
-Therma-Rest Self Inflating Pad- 2lb 8oz
I use a ProLite 4 at 1.5 lbs. In the winter you might need more than a Prolite 4. Yours might be fine for the winter. Check the R rating. You could go a lot lighter for 3 season use but I like the comfort. I am looking to lighten my load here.
-Fire Kit-3 lbs
Mine consists of: Alcohol Hand Gel (1 oz at 1.3 oz), Matches (4) & Trick Candles (4) (.35 oz), Spark-Lite & Tinder (6) (.35 oz), a Fresnel lens, and an Esbit tablet. All well under 3 oz and I could be accused of overkill.
I've compared my gear to yours, not to say mine is the best but to simply show an alternative. Mine is a work in progress that works for me and may not work for others. For certain cases your gear is entirely appropriate, but I think you are embarking on a fun learning curve.
I see you are a member, but possibly new enough that you haven't had a chance to read all the content on the site. I would recommend doing so and creating a complete gear list, including every thing you would take from the skin out. This will give you a bigger picture of how things work together. Then you can enjoy the testing (outings), which is what we are all here for, I presume.
