Thanks for the info about Crown stock SS coils. Can't do anything with a CSV on my VTC mini, so the only way I'm getting it to run OK right now is turning watts way down to just a bit over what I'd be running in regular wattage mode and turning the temp way up. That way it pretty much just runs just like watts mode with a bit headroom for dry coil protection? In theory, right? Anyway, about to run the tank dry, so we'll see if it even works.
