I just ordered 2mm hollow ekowool and xs-116 from kidney puncher with a bunch of other supplies when you stock up the shipping isn't terrible. They are more expensive but ya know what, they have great quality supplies for rebuildables all in one place so willing to pay the price to support that. Once I get everything I will let you know how it goes, I'll be putting both on a 1/16 7x7 316 steel cable wrapped in 30g kanthal (maybe ribbon wire) attached to a Doc Dave Mini Micro on a Precise Simplicity 14500. Target is 1.5ohms.
