I use a setup very similar to the OP. I stocked up DEEP on the GoingGear Numyth capsule factory seconds. They were so cheap I couldn't afford not to. I carry a spare CR123 on my keychain (1 capsule section), 3x CR123 in my bag (3 capsule sections), and when I need an 18650 I use 2 capsule sections. They're damn near bombproof and easily re-configurable to whatever my needs are.
I also have a Versati titanium single CR123 capsule, but it was so much heavier than my GoingGear capsules I relegated it to bag duty.
