I always space as the flavor is much better in my experience. Especially makes sense with ribbon wire as it's so thin that you'd have to do something like the tin man build for a contact coil. Btw I just tested a few different sizes of SS ribbon wire and round wire spaced parallel coils destroyed them in terms of flavor.
Not sure I read that right. You're saying the spaced round wire was superior to the SS flat or ribbon wire?
I wish I didn't even waste the money on it. I'm glad I tried it but yeah it sucked in comparison. I do 26g SS builds. If you do one make sure there's no spacing in between the wires themselves (but obviously you want space between wraps).
Now here I assume you're talking about winding my own wire? That's a bridge too far for me.
Also 28g is easier to work with in that it's easier to get out the spaces between the two wires but 26g stays in place easier. I don't mind either but for regulated mods I do 26g. I just like the way it heats up better.
OK, well the SS316L round wire I have always used is 24g. I don't combine it or twist it into anything else. Just that wire using spaced 3mm - 3.5mm coils in a dual coil tank (Aromamizer). Which I always loved until I recently got a Wotofo Profile and built that with SS316L mesh... also getting a Serpent SMM at the same time which included a few Nichrome flat staple coils (contact coils).
The Profile (dripper) blows the rest out of the water for flavor (since it's a dripper), and cannot taste the SS mesh at all. (It comes with Kanthal mesh, but I prefer SS mesh.)
The Serpent is not as flavorful, of course, and I did taste some metal when the NiCr80 coil was new (s/h lightly dry burned), but don't detect a metal taste anymore.
So after vaping the Profile and Serpent for a week exclusively, went back to the Aromamizer and all I could taste was SS from the round wire, spaced coil builds. A taste I'd apparently gotten used to for so long, I wasn't picking it up until I got away from it for awhile. (Wish I could use SS mesh in that tank.)
So that's what precipitated my OP here... wondering if SS316L flat ribbon wire made with contact coils would be a better experience than the round wire. Though I realize it's all subjective, and from the replies sounds like spaced is better for TC anyway. So guess it comes down to, will the SS ribbon wire have less of a SS taste to it than the round wire. And that will be had by trying it.
I do have flat Nichrome on the way for the Serpent, so maybe I'll try that in the Aromamzer too and see how it goes. Just not liking that SS round wire taste anymore, and am so happy I don't have it with the SS mesh.
