I have a parallel 316 going now.
Parallel 26g, ss316l, 3mm, 8/7wrap. .25ish. Smooth sailing.
That's almost exactly (0.29 @3.5) what I have in a uh... Bachelor Nano (losing track).
It's... sssssssssssssmmokin'
It played hob on the DNAs for a bit though (spacing shifted maybe) so I was considering twisted instead. Or just a big fat 24g
Finally found WiresandStuff for fatter 430 gauges but I might get more 28g just to twist up.
