Did this for myself, so I thought I'd share it here. Using specs from TEMPCo
and my favorite 8/7 wrap 0.5Ω micro coil as a baseline for calculations:
Different leg length could vary these ± 0.1Ω due to rounding.
Let me know if you find any errors and I'll correct them.
I'd torch any of these first with a $4 Ronson Jetlite Torch butane lighter.
Burns off nasty tasting machining oil and makes it easier to work with.
IMHO, I wouldn't use anything thinner than 30AWG on a mechanical REO YMMV
edit to add: (fewer wraps of thinner wire = less wire to wick contact area)

An 8/7 wrap micro coil on a Reomizer 2:
26 AWG Nichrome 60 = 0.5Ω @ 0.1272" wide
based on the above:
26 AWG Kanthal A1 = 0.6Ω @ 0.1272" wide
27 AWG Kanthal A1 = 0.8Ω @ 0.1136" wide
28 AWG Nichrome 60 = 0.8Ω @ 0.1008" wide
28 AWG Kanthal A1 = 1.0Ω @ 0.1008" wide
29 AWG Kanthal A1 = 1.2Ω @ 0.0904" wide
30 AWG Nichrome 60 = 1.3Ω @ 0.0800" wide
30 AWG Kanthal A1 = 1.6Ω @ 0.0800" wide
31 AWG Kanthal A1 = 2.0Ω @ 0.0712" wide
32 AWG Nichrome 60 = 2.0Ω @ 0.0640" wide
32 AWG Kanthal A1 = 2.5Ω @ 0.0640" wide
Different leg length could vary these ± 0.1Ω due to rounding.
