The perfect all purpose wire, I use 26G SS316L for all of my RTA's and RDA's.
I love the fact I can use it in both TC mode on my DNA/Yihi/other brand mods that can do SS TC, and it performs superbly with the CSV file downloaded from steam engine on the DNA mods uploaded through Escribe, and also in standard power builds.
I use it on my mechs as well, and find it to be the perfect gauge for something that fires up quickly, but isn't super low resistance.
I would say stealth vapes wire is the best I have tried, especially for TC.
