I've been using .8 x .2 SS spaced for a long time now.I'd not go thinner than 0.1mm and not thicker than 0.2mm. Width wise it depends on how much power you're comfortable to use, anything from 0.5mm to 2.5mm would be fine (the latter has already ultra low resistance).
For a start I'd recommend 0.8mm*0.2mm, it's one of the easier to handle (has about the same size as a 2*28g+40g fused clapton).
Oops, didn't realize it worked that way. I might be behind some months...![]()
Love it, larger surface area than round and fast ramp with lower power, compared to Clapton's etc..
