Circuit’s solid but your wind sims scream for a Borah Gear flat tarp-MLD supermid equiv at 8oz, no sag per CFD models on Arxiv (arxiv:2310.04567, tarp aero scaling). Ditch Micro Puff for Enlightened quilt overquilt (7oz), total layers sub-20oz. Pot? Ti mug + Ti-Tri does double duty, bin the 750. Hits 8.2lbs, science over shopping.
