I dont like going to low with SS as it feels hotter then Kanthal and rtamps up faster so you cant draw like you can with Kanthal. I like a Squared/Polished 3mm ID Coil with some 24g 316L on a Tube. For a box Ive tried a 3 core Fused Clapton Single Coil and it was decent, nothing award winning though.
I find it cooler than kanthal, way cooler than the .15 macros 22ga duals I wasrunning a few days ago and just took out some 24 ga parallel duals ohming at .12. I really like the fast ramp up but I don't know how much wire I can cram in the rda before it's overkill and draining my battery before it ramps up.
That you can find out at http://www.steam-engine.org/coil.asp. Look at the Heat Capacity value, once you entered the other parameters. You can use the steam engine as a guideline only! The actual build should be tested with an Ohm meter.
I use the engine every time and also use the battery drain one a fair amount just to see what I'm pushing the vtc4's at, I never understood fully the heat capacity and heat flux. What is the capacity in reference to ramp up time?
Click on the "How it works" bottom left of the page, and scroll down. You'll find the explanation there. However, don't ask me what good values are for the heat capacity.
I'm still experimenting myself with 316L wire, my preferred wire, due to the ability of being used in either power, or TC mode (in case I should really run out of power on my DNA200 mods).
Square and Round Parallel is where its at
The juice rolls off the round wire down onto the flat wire
